Ice cubes are dropped into a glass of water. You notice that the glass of water becomes colder and condensation appears. Later in the day, you notice the glass of water is now room temperature and there is no more condensation. Which of the following concepts describes this process?

As heat energy is added to a cube of ice, it begins to melt into liquid water. Which of the following correctly identifies the change in temperature and the change in internal energy of the ice as heat is added to it?

Ice can be used to counter the effects of overeating. How many kilograms of ice at would one have to eat in order to cancel the effect of eating ? Assume body temperature to be .

Specific heat of water =

Specific heat of ice =
