The relation between two specific heats (in cal/mol) of a gas is:
1.  ${\mathrm{C}}_{\mathrm{P}}-{\mathrm{C}}_{\mathrm{V}}=\frac{\mathrm{R}}{\mathrm{J}}$

2.  ${\mathrm{C}}_{\mathrm{V}}-{\mathrm{C}}_{\mathrm{P}}=\frac{\mathrm{R}}{\mathrm{J}}$

3.  ${\mathrm{C}}_{\mathrm{P}}-{\mathrm{C}}_{\mathrm{V}}=\mathrm{J}$

4.  ${\mathrm{C}}_{\mathrm{V}}-{\mathrm{C}}_{\mathrm{P}}=\mathrm{J}$

Given below are two statements:
 Assertion (A): The ratio $$C_p\over C_v$$ is more for helium gas than for hydrogen gas. Reason (R): Atomic mass of helium is more than that of hydrogen.

 1 Both (A) and (R) are true and (R) is the correct explanation of (A). 2 Both (A) and (R) are true but (R) is not the correct explanation of (A). 3 (A) is true but (R) is false. 4 Both (A) and (R) are false.

The figure shows a process for a gas in which pressure (P) and volume (V) of the gas change. If ${C}_{1}$ and ${C}_{2}$ are the molar heat capacities of the gas during the processes AB and BC respectively, then:

1. ${C}_{1}={C}_{2}$

2. ${C}_{1}>{C}_{2}$

3. ${C}_{1}<{C}_{2}$

4. ${C}_{1}\le {C}_{2}$

If $$C_p$$ and $$C_v$$ denote the specific heats (per unit mass) of an ideal gas of molecular weight $$M$$ (where $$R$$ is the molar gas constant), the correct relation is:
1. $$C_p-C_v=R$$
2. $$C_p-C_v=\frac{R}{M}$$
3. $$C_p-C_v=MR$$
4. $$C_p-C_v=\frac{R}{M^2}$$
