If 70 cals of heat is required to raise the temp. of 2 moles of an ideal gas at constant pressure from 30 0 C to 35 0 C, then the amount of heat required to rise the temperature of same gas through same range at constant volume is -
Text Solution
Verified by ExpertsThe correct answer is:
A
The heat required to raise the temperature of gas, at constant volume 
is
and at constant pressure is
Also, 
(iii)
From Eqs. (i), (ii) and (iii), we get
