An ice cube tray makes a dozen 20.0 g ice cubes. If the ice cube tray is filled
with 0.00°C water, and then frozen into
ice cubes, find Q, the change in heat
energy of the water.

A calorie is defined as the amount of heat required to change the temperature of one gram of liquid water by one degree Celsius (or one degree Kelvin). 1 cal = 4.184 J 1 J = 1 Ws = (1 Ws) (1/3600 h/s)

Explanation:

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
