Heat and Thermal ExpansionHard
Question
Cp is always greater than CV due to the that : -
Options
A.No work is being done on heating the gas at constant volume.
B.When a gas absorbs heat at constant pressure its volume must change so as to do some external work
C.The internal energy is a function of temperature only for an ideal gas.
D.For the same rise of temperature, the internal energy of a gas changes by a smaller amount at constant volume than at constant pressure.
Solution
At constant volume. work done by gas is zero.
