1. When an ideal diatomic gas is heated at constant pressure, the fraction of the heat energy supplied which increases the internal energy of the gas is
Text Solution
Verified by ExpertsThe correct answer is:
D
When a gas is heated at constant pressure then its one part goes to increase the internal energy and another part for work done against external pressure i.e. 
⇒ ⇒ 
So fraction of energy that goes to increase the internal energy 
[As 
for diatomic gas]
