a)What is the change in entropy of 2 g of steam at 100° C as it condenses to water at 100° C?
b) What is the most that you can say about the amount (ΔS) by which the entropy of the rest of the universe increases in the process above?
ΔS > ___ J/K

ΔS > ___ J/K
-
Quantity of heat lost by steam on condensing
- 2260 kJ = 2.26e+6 J
Loss in entropy = -0.002*2.26e+6 / 373 = - 12.12J/K
The system looses entropy.
No heat is given out to the surroundings and there is no change in the entropy of the surroundings due to this process.
