The specific heats at constant pressure is greater than that of the same gas at constant volume because

1. At constant pressure work is done in expanding the gas

2. At constant volume work is done in expanding the gas

3. The molecular attraction increases more at constant pressure

4. The molecular vibration increases more at constant pressure

The specific heat of a gas:

1. has only two values \(Cp\) and \(Cv\).   
2. has a unique value at a given temperature.
3. can have any value between 0 and  ∞.
4. depends upon the mass of the gas.
