Under Article 143 of the Indian Constitution, the President of India can seek the opinion of the Supreme Court on questions of law or matters of public importance. This advisory role strengthens the judiciary's role in governance.
• The Canadian model of federalism also influenced the Indian Constitution in other ways, such as the division of powers between the Union and States.
• The advisory jurisdiction provides a mechanism for resolving legal uncertainties, ensuring clarity on constitutional or legal matters. This is a hallmark of the federal structure influenced by Canada.
• None of the other options listed (Rule of Law, Impeachment of the President, Fundamental Duties) were borrowed from Canada. These features have their origins in other sources like the British Constitution, U.S. Constitution, or Soviet principles.
• This distinctive feature in India ensures the Supreme Court’s role in offering legal counsel to the executive, promoting democratic accountability and rule of law.

The correct answer is Pressure and Temperature.

Key Points

• The state of a substance (solid, liquid, or gas) is primarily determined by its pressure and temperature. These two factors control the phase transitions between different states of matter.
• Temperature: Higher temperatures provide particles with more kinetic energy, allowing them to overcome intermolecular forces and transition from solid to liquid (melting) or liquid to gas (evaporation).
• Pressure: Increasing pressure forces particles closer together. At high pressures, gases can condense into liquids or even solids. Conversely, reducing pressure can allow substances to transition to gaseous states more easily.
• For example, water exists as ice, liquid water, or steam depending on the specific combination of pressure and temperature. At standard atmospheric pressure, water freezes at 0°C and boils at 100°C.
• Phase diagrams are used to represent the relationship between pressure, temperature, and the state of a substance. They show the conditions under which a substance exists as a solid, liquid, or gas.

Additional Information

• Density and Viscosity: These properties are characteristics of a substance and do not determine its state. For example, honey is highly viscous but is always in a liquid state under normal conditions. Similarly, density changes with the state but does not directly define the state of matter.
• Pressure and Density: While density is influenced by pressure (e.g., compressing a gas increases its density), it is not the sole determinant of a substance’s state. Pressure and temperature together influence phase changes.
• Temperature and Weight: Weight is a measure of gravitational force on a substance and has no relevance in determining its state. Temperature, however, is a critical factor in phase transitions.
• Phase Transitions: Common phase transitions include melting (solid to liquid), freezing (liquid to solid), vaporization (liquid to gas), condensation (gas to liquid), sublimation (solid to gas), and deposition (gas to solid).
• Critical Point: At the critical temperature and pressure, the distinction between liquid and gas disappears, and the substance exists as a supercritical fluid. This is a unique state of matter with properties of both gases and liquids.

Important Points

• Triple Point: The triple point is the specific pressure and temperature at which all three states of a substance (solid, liquid, and gas) coexist in equilibrium. For water, this occurs at 0.01°C and 611.657 Pascals.
• Real-life Applications: Understanding pressure and temperature is crucial in fields like meteorology, material science, and engineering. For example, refrigeration systems rely on controlling pressure and temperature to achieve desired cooling effects.
• Examples of Phase Changes: Dry ice (solid CO2) sublimates directly into gas at atmospheric pressure, while metals like iron transition between solid and liquid phases during smelting processes.
• Phase Diagrams: These graphical representations help visualize the conditions under which substances change states, aiding in industrial and scientific applications such as chemical synthesis and material design.
