Which of the two 1kg of solid iron or 1kg of liquid iron has the greater entropy?
Answer to Problem 19Q
Solution:
1kg of liquid iron has the greater entropy.
Explanation of Solution
As we know that the entropy is defined as the degree of randomness and the molecules of 1 kg liquid iron are more random than the molecules of the 1 kg solid iron. Molecules of liquid iron has more thermal energy.It is also known that the solid iron is heated to melt and get the liquid iron.So, adding the heat to get the liquid iron will also increase the entropy of the liquid iron.
