Which of the following is insensitive to changes in pressure ?
Correct answer: B. Both B. and C.
- A. Heat of vaporisation
- B. Both B. and C.
- C. Heat of fusion
- D. Melting point
Explanation
The melting point and heat of fusion are comparatively insensitive to pressure, whereas the heat of vaporisation changes appreciably with pressure because vapour volume changes greatly. Therefore both B and C apply.

In Joule's experiment, an insulated container contains 20 kg of water initially at 25°C. It is stirred by an agitator, which is made to turn by a slowly falling body weighing 40 kg through a height of 4 m. The process is repeated 500 times. The acceleration due to gravity is 9.8 ms-2. Neglecting the heat capacity of agitator, the temperature of water (in °C) is________________?
