1. $$8.3$$ J
2. $$16.6$$ J
3. $$25$$ J
4. $$29$$ J

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. $$C_p-C_v=\frac{R}{M^2}$$
