Answer to Question #75353 in General Chemistry for lilly

Question

A mixture of 50.0 g of ice and 100.0g of liquid water is kept at a steady 0 degrees Celsius in a closed container. You wait an hour and weigh them again. What would you predict the resulting masses to be?

Answer 1

Answer:
Masses will be the same.
(Surely, if initial temperatures of the ice and the water were 0 degrees Celsius).
Ice needs energy to melt, and water could release energy while crystallization.
These energy amounts are the same. Also consider that no energy could be
transferred from water to ice at 0 degrees Celsius. Physically, there is no
temperature gradient in this closed system.
