Section A – Very Short Answers Type Questions (2 Marks Each)
Question (QP Code- 0119) | TS Inter 1st Year Physics Answer Key 2025 |
|---|---|
1. What is the contribution of S. Chandrashekhar to Physics? | S. Chandrasekhar, an Indian-American astrophysicist, made a significant contribution to physics by formulating the Chandrasekhar Limit . This limit defines the maximum mass (approximately 1.4 times the mass of the Sun) that a white dwarf star can have before it collapses under its own gravity, leading to a supernova explosion or the formation of a neutron star or black hole. |
2. Why do we have different units for the same physical quantity? | Different units for the same physical quantity exist due to historical conventions, regional preferences, and practical applications in various fields. For example, length can be measured in meters (SI unit) or feet (imperial unit) depending on the context and system used. |
3. If P = 2i + 4j + 14k and Q = 4i + 4j + 10k, find the magnitude of P+Q. | 26 |
4. If a bomb at rest explodes into two pieces, the pieces must travel in opposite directions. Explain. | When a bomb at rest explodes into two pieces, the total momentum before and after the explosion must remain zero due to the conservation of momentum. Since the initial momentum is zero, the pieces must travel in opposite directions with equal and opposite momenta to cancel each other out. |
5. Give the expression for the excess pressure in an air bubble inside the liquid. | The excess pressure inside an air bubble in a liquid is given by the expression ΔP=2σ/r, where σ is the surface tension of the liquid and r is the radius of the bubble. This arises due to the surface tension acting across the bubble's curved surface. |
6. What are waterproofing agents and water-wetting agents? What do they do? | Waterproofing agents are substances that repel water, reducing a surface's ability to absorb it, like silicones used on fabrics. Water wetting agents, or surfactants, reduce surface tension, enhancing water's ability to spread and penetrate surfaces, as seen in detergents. |
7. Does a body radiate heat at 0 K? Does it radiate heat at 0 o C? | A body does not radiate heat at 0 K (absolute zero) as it has no thermal energy, but it does radiate heat at 0°C (273 K) as it still possesses thermal energy above absolute zero. |
8. What is latent heat of vaporization? | The latent heat of vaporization is the amount of heat energy required to change a unit mass of a substance from liquid to vapour at its boiling point without a change in temperature. |
9. The absolute temperature of a gas is increased 3 times. What will be the increase in rms velocity of the gas molecule? | 1.732 times (approx.) |
10. When does a real gas behave like an ideal gas? | A real gas behaves like an ideal gas at high temperatures and low pressures, where intermolecular forces become negligible and the volume of gas molecules is insignificant compared to the container volume. These conditions align with the assumptions of the ideal gas law. |
