1.	How does second law of thermodynamics explain expansion of gas?
Answer» Since from second law,. d S ≥ O d S = change in entropy During the expansion of gas, the thermodynamic probability of gas is larger and hence its entropy is also very large. Since form second law, entropy cannot decrease ∴ following the second law, gas molecules move from one partition to another.

Answer»

Since from second law,.

d S ≥ O d S = change in entropy

During the expansion of gas, the thermodynamic probability of gas is larger and hence its entropy is also very large. Since form second law, entropy cannot decrease

∴ following the second law, gas molecules move from one partition to another.
