Explanation :
1) N2 gas is heated from 2 oC to 19.0 oC . so randomness of molecules increase.so entropy increases.
so delta S > 0
2) NH3 is heated from -17 oC to 78.0 oC . so randomness of molecules increase.so entropy increases.
so delta S > 0
3) cooling and compression leads to decrease in entropy
