In a process, temperature and volume of one mole of an ideal monoatomic gas are varied according to the relation VT = K, where K is a constant. In this process the temperature of the gas is increased by Δ T. The amount of heat absorbed by gas is (R is gas constant) :

1. 2 1 KR Δ T
2. 2 1 R Δ T
3. 2 3 R Δ T
4. 3 K 2 Δ T

Correct answer: 2 1 R Δ T
