Applicability of Clausius-Clapeyron Equation is subject to the condition that the __________________?
Correct answer: C. Both A. & B.
- A. Vapor follows ideal gas law
- B. Volume in the liquid state is negligible
- C. Both A. & B.
- D. Neither A. nor B.
Explanation
The commonly used integrated Clausius-Clapeyron form assumes an ideal-gas vapour and neglects the liquid molar volume relative to the vapour molar volume. Hence both stated conditions are required for this simplified equation.

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________________?
