problem 3 10 an ice cube mass 30 g at 0 c is left sitting on the kitch
Problem 3.10. An ice cube (mass 30 g) at 0°C is left sitting on the kitchen table,
where it gradually melts. The temperature in the kitchen is 25°C.
(a) Calculate the change in the entropy of the ice cube as it melts into water
at 0°C. (Don't worry about the fact that the volume changes somewhat.)
(b) Calculate the change in the entropy of the water (from the melted ice) as
its temperature rises from 0°C to 25°C.
(c) Calculate the change in the entropy of the kitchen as it gives up heat to
the melting ice/water.
(d) Calculate the net change in the entropy of the universe during this process.
Is the net change positive, negative, or zero? Is this what you would expect?
