Question

Statement-1 : At a given temperature the specific heat of a
gas at constant volume is always greater than its specific
heat at constant pressure.
Statement-2 : When a gas is heated at constant volume
some extra heat is needed compared to that at constant
pressure for doing work in expansion.

Answer 1

Answer:

Explanation:For an ideal gas, the heat capacity at constant pressure is larger than than that at constant volume because. more collisions occur per unti time when volume is kept constant. At constant volume nCvΔT=ΔU.
