Physics
Two substances, A and B, have the same mass. Substance A has a higher specific heat capacity than substance B. What consequences would you expect when these substances are subjected to the same amount of heat energy?
- Substance A will experience a smaller temperature change than substance B.
- Substance A will experience a larger temperature change than substance B.
- Both substances will experience the same temperature change.
- Either of them can show a greater change in temperature as the temperature change depends on factors other than specific heat capacity.
Answer
Substance A will experience a smaller temperature change than substance B.
Reason — Specific heat capacity tells us how much heat is needed to raise the temperature of a substance. A higher specific heat means the substance absorbs more heat without a big temperature rise. So, with the same heat energy and mass, Substance A (with higher specific heat) will heat up less than Substance B.

A student traces the path of a ray of light through a glass prism for different angles of incidence. He analyses each diagram and draws the following conclusion:
I. On entering the prism, the light ray bends towards its base.
II. Light ray suffers refraction at the point of incidence and at the point of emergence while passing through the prism.
III. An emergent ray bends at a certain angle to the direction of the incident ray.
IV. While emerging from the prism at the second surface, the angle of refraction is less than the angle of incidence at that surface.
Which of the above inferences are correct?
- I, II and III
- I, III and IV
- II, III and IV
- All of these.
