Question

One mole of oxygen is heated from 0oC, at constant pressure, till its volume increases by 10%. The specific heat of oxygen, under these conditions is 0.22 cal g – 1 K – 1. The amount of heat required (in joules) is

Solution

Correct option is

 

For an enclosed gas at constant pressure  (Charles’ law). Hence, to increase the volume by 10%, the absolute temperature must be increased by 10%. Initial temperature is T = 273 k. The final temperature must be  Therefore, rise in temperature = 300.3 – 273 = 27.3 K.
