Problem

You have a sample containing 15 grams of solid ethanol together with 15 g of liquid ethanol. The sample is at the freezing temperature of ethanol, -114C. What happens when you initially place this mixture in a deep freezer which is held at -180C and energy flows out of the sample in the form of heat? 

A. The temperature of the sample decreases while the liquid ethanol freezes.

B. The temperature of the sample remains constant while the liquid ethanol freezes.

C. The temperature of the sample remains constant while the solid ethanol melts.

D. The temperature of the sample increases while the liquid ethanol freezes.

E. The temperature of the sample remains constant and the relative amount of liquid and solid ethanol remains constant.
