The correct answer is Both A and B are false .

Key Points

• Explanation of Statement A:
• Statement A claims that all objects must change from solids into liquids before changing into gases, which is incorrect.
• This process is known as melting (solid to liquid) followed by vaporization (liquid to gas), but it is not mandatory for all substances.
• Some substances can directly change from a solid to a gas through a process called sublimation, bypassing the liquid phase.
• Examples of substances that undergo sublimation include dry ice (solid CO₂) and camphor.
• Sublimation occurs under specific temperature and pressure conditions, depending on the substance.
• The phase change from solid to gas is a physical process and does not involve chemical changes.
• Sublimation is commonly observed in everyday life, such as the disappearance of naphthalene balls used in closets.
• The process is also used in scientific applications, such as freeze-drying food and pharmaceuticals.
• Therefore, Statement A is scientifically inaccurate because not all substances require an intermediate liquid phase to become gases.

Additional Information

• Explanation of Statement B:
• Statement B claims that evaporation is the process by which solids can change into gases, which is incorrect.
• Evaporation is the process by which liquids change into gases at temperatures below their boiling point.
• It occurs at the surface of a liquid and is influenced by factors like temperature, humidity, and surface area.
• For solids to change into gases, the correct process is sublimation, not evaporation.
• Evaporation is a common phenomenon observed in daily life, such as the drying of water from clothes or the disappearance of puddles after rain.
• It is a key component of the water cycle, where water evaporates from oceans, lakes, and rivers to form clouds.
• Evaporation is different from boiling, which occurs at a specific temperature (boiling point) and involves the entire liquid.
• Solids do not undergo evaporation; instead, they may sublimate under specific conditions.
• Therefore, Statement B is scientifically inaccurate because evaporation applies only to liquids, not solids.
• Additional Facts:
• Phase changes in matter (solid, liquid, gas) are governed by temperature and pressure conditions.
• The triple point of a substance is the temperature and pressure at which all three phases (solid, liquid, gas) coexist in equilibrium.
• Deposition is the reverse process of sublimation, where a gas changes directly into a solid without becoming a liquid.
• Examples of deposition include the formation of frost on cold surfaces and the creation of snowflakes in clouds.
• Understanding phase changes is crucial in fields like meteorology, material science, and engineering.
• The study of phase transitions helps in developing technologies like refrigeration, air conditioning, and thermal management systems.
• Both evaporation and sublimation are endothermic processes, meaning they absorb heat from the surroundings.
• These processes play a vital role in Earth's climate system and the distribution of water and energy.

Given:

Radius of the base and height of the cylinder are in the ratio 7 : 3.

Volume of the cylinder = 12474 cm³

Use π = 22/7

Formula Used:

Total surface area of the cylinder = 2πr(r + h)

Volume of the cylinder = πr²h

Calculation:

Let the radius of the base be 7x and the height be 3x.

Volume of the cylinder = πr²h

⇒ (22/7) × (7x)² × (3x) = 12474

⇒ (22/7) × 49x² × 3x = 12474

⇒ (22/7) × 147x³ = 12474

⇒ 22 × 21x³ = 12474

⇒ 462x³ = 12474

⇒ x³ = 27

⇒ x = 3

So, the radius of the base = 7x = 7 × 3 = 21 cm

Height of the cylinder = 3x = 3 × 3 = 9 cm

Total surface area of the cylinder = 2πr(r + h)

⇒ 2 × (22/7) × 21 × (21 + 9)

⇒ 2 × (22/7) × 21 × 30

⇒ 2 × 22 × 3 × 30

⇒ 2 × 22 × 90

⇒ 3960 cm²

The total surface area of the cylinder is 3960 cm².

Given:

Annual salary in 2008 = ₹48,580

This was 25% more than his salary in 2007.

Formula Used:

If the salary in 2007 is X, then:

2008 Salary = 2007 Salary + 25% of 2007 Salary

₹48,580 = ₹X + 0.25 × ₹X

Calculations:

₹48,580 = ₹X + 0.25 × ₹X

₹48,580 = ₹X(1 + 0.25)

₹48,580 = ₹X × 1.25

→ ₹X = ₹48,580 / 1.25

→ ₹X = ₹38,864

∴ Ram's salary in 2007 was ₹38,864.

Given:

Price reduction = 25% = 0.25

Increase in sale = 30% = 0.30

Formula used:

Net effect (%) = (x + y + xy/100)%

Where x = -25% (reduction) and y = 30% (increase)

Calculation:

Net effect = (-25 + 30 + (-25 × 30)/100)%

⇒ Net effect = (5 - 7.5)%

⇒ Net effect = - 2.5%

∴ The net effect on the daily sale receipts is a decrease of 2$\frac{1}{2}$%.

Given:

Speed 1 = 10 km/h

Speed 2 = 14 km/h

Extra distance covered at 14 km/h = 20 km

Calculation:

Let actual distance = D km

According to the question:

(D/10) = (D + 20)/14

Cross-multiplying:

14 × D = 10 × (D + 20)

14D = 10D + 200

14D - 10D = 200

4D = 200

D = 200/4

D = 50 km

∴ The actual distance travelled by him is 50 km.

Given:

The numbers are 72, 81, 90, 68, 61.

Formula Used:

Population after n years = Initial Population × (1 + growth rate/100)^{number of years}

Calculation:

Population after first year = 10,000 × (1 + 20/100)

⇒ Population after first year = 10,000 × 1.2

⇒ Population after first year = 12,000

Population after second year = 12,000 × (1 + 20/100)

⇒ Population after second year = 12,000 × 1.2

⇒ Population after second year = 14,400

Population after third year = 14,400 × (1 - 10/100)

⇒ Population after third year = 14,400 × 0.9

⇒ Population after third year = 12,960

Population after fourth year = 12,960 × (1 - 5/100)

⇒ Population after fourth year = 12,960 × 0.95

⇒ Population after fourth year = 12,312

The current population of the city after four years is 12,312.

Shortcut Trick Population after fourth year = 10,000 × (1 + 20/100) × (1 + 20/100) × (1 - 10/100) × (1 - 5/100)

⇒ 10,000 × 1.2 × 1.2 × 0.9 × 0.95

⇒ 12,312

Given:

8 men can complete a work in 6 hours.

Formula Used:

Work = Men × Time

Calculation:

Let the total work be W.

Work done by 8 men in 6 hours:

W = 8 × 6

Work done by 12 men in t hours:

W = 12 × t

Since the work is the same:

8 × 6 = 12 × t

⇒ t = (8 × 6) / 12

⇒ t = 48 / 12

⇒ t = 4

12 men can complete the same work in 4 hours.

Given:

Cost Price (CP) of each water bottle = ₹18

Selling Price (SP) of each water bottle = ₹20

Number of water bottles = 10

Formula used:

Total CP = Number of bottles × CP per bottle

Total SP = Number of bottles × SP per bottle

Profit % = (Profit / Total CP) × 100

Calculation:

Total CP = 10 × 18 = ₹180

Total SP = 10 × 20 = ₹200

Profit = Total SP - Total CP

⇒ Profit = ₹200 - ₹180 = ₹20

Profit % = (20 / 180) × 100

⇒ Profit % = 11$\frac{1}{9}$%

∴ Lalita’s overall profit percentage is 11$\frac{1}{9}$%

Given:

Market Price (MP) = 25% above Cost Price (CP)

Discount = 12%

Formula used:

Gain % = [(SP - CP) / CP] × 100

Calculation:

Let the Cost Price be ₹100.

Market Price = CP + 25% of CP = 1.25 × CP

Market Price = 1.25 × 100 = ₹125

Selling Price (SP) = MP - 12% of MP = MP × 0.88

Selling Price = 0.88 × 125 = ₹110

Gain = SP - CP = 110 - 100 = ₹10

Gain % = (10/100) × 100 = 10%

∴ The gain in the deal is 10%.

Shortcut Trick

The difference between the Total Surface Area (3πr²) and the Curved Surface Area (2πr²) of a hemisphere is simply the area of its circular base (πr²).

Difference = Area of base = πr²

Difference = (22/7) × 21 × 21 = 22 × 3 × 21

Difference = 66 × 21 = 1386 cm²

∴ The correct answer is 1386 cm².

Alternate Method

Given:

Radius of the hemisphere (r) = 21 cm

Value of π = 22/7

Formula Used:

Curved Surface Area (CSA) of hemisphere = 2πr²

Total Surface Area (TSA) of hemisphere = 3πr²

Calculations:

⇒ Curved Surface Area (CSA) = 2 × (22/7) × 21 × 21

⇒ CSA = 2 × 22 × 3 × 21 = 2772 cm²

⇒ Total Surface Area (TSA) = 3 × (22/7) × 21 × 21

⇒ TSA = 3 × 22 × 3 × 21 = 4158 cm²

⇒ Difference = TSA − CSA

⇒ Difference = 4158 − 2772 = 1386 cm²

∴ The correct answer is 1386 cm².

Additional Information

Surface Area of a Sphere

A sphere has only one surface area, which is 4πr². A hemisphere is half of a sphere but adds a flat circular base.

Volume of a Hemisphere

Base Area Relationship

The TSA of a hemisphere is always 1.5 times its CSA because 3πr² = 1.5 × (2πr²).

Given:

Total amount = ₹4000

Rate of interest for first part = 3% p.a.

Rate of interest for second part = 5% p.a.

Total annual interest = ₹144

Formula used:

Total interest = Interest on first part + Interest on second part

SI = (P × R × T) ÷ 100

Calculation:

Let the first part invested at 3% be ₹x.

Then, the second part invested at 5% will be ₹(4000 - x).

According to the question:

(x × 3 × 1)/100 + ((4000 - x) × 5 × 1)/100 = 144

⇒ 0.03x + 0.05(4000 - x) = 144

⇒ 0.03x + 200 - 0.05x = 144

⇒ -0.02x = 144 - 200

⇒ -0.02x = -56

⇒ x = 56 ÷ 0.02

⇒ x = 2800

∴ The amount invested at 3% per annum simple interest is ₹2800.

Given:

Smallest prime number between 1 and 100 = 2

Difference = 97 - 2

∴ The difference between the smallest and the largest prime numbers between 1 to 100 is 95.

Given:

We need to find the smallest four-digit number that is divisible by 15, 25, 40, and 75.

Formula Used:

The smallest number divisible by multiple numbers is the Least Common Multiple (LCM) of those numbers.

Calculation:

First, find the LCM of 15, 25, 40, and 75.

Prime factorization:

15 = 3 × 5

25 = 5²

40 = 2³ × 5

75 = 3 × 5²

LCM is obtained by taking the highest powers of all prime factors.

LCM = 2³ × 3 × 5²

⇒ LCM = 8 × 3 × 25

⇒ LCM = 600

Now, find the smallest four-digit number divisible by 600.

Smallest four-digit number = 1000

Divide 1000 by 600 and round up to the next whole number.

⇒ 1000 / 600 ≈ 1.67

⇒ Next whole number = 2

Multiply LCM by 2:

⇒ 600 × 2 = 1200

The smallest four-digit number divisible by 15, 25, 40, and 75 is 1200.
