Entropy of the system decreases, when
A. Snow melts into water
B. A gas expands spontaneously from high pressure to low pressure
C. Water is converted into ice
D. Both B & C
Answer: Option D
Solution(By Examveda Team)
Since, the degree of randomness decreases when the water is converted to ice the entropy decreases and also in an similar way when the gas is expanding from high pressure to low pressure the entropy increases.Related Questions on Chemical Engineering Thermodynamics
