A gas is allowed to expand under reversible adiabatic conditions then :
1 \(\Delta \mathrm{G}=0\)
2 \(\Delta \mathrm{T}=0\)
3 \(\Delta S=0\)
4 None of these
Explanation:
\( \Delta S=\frac{q_{\text {rev }}}{T} \) \( q=0 \text { for adiabatic process } \) \( \therefore \quad \Delta S & =0 \)

The work done by a system is \(8 \mathrm{~J}\) when \(40 \mathrm{~J}\) heat is supplied to it. The change in internal energy of the system during the process :
1 \(32 \mathrm{~J}\)
2 \(40 \mathrm{~J}\)
3 \(48 \mathrm{~J}\)
4 \(-32 \mathrm{~J}\)
Explanation:
\( d U & =q+w \) \( w & =\text { expansion } \) \( \therefore \quad d U & =q-w \) \( =40 \mathrm{~J}-8 \mathrm{~J} \) \( =32 \mathrm{~J} \)
