Why was a styrofoam cup used instead of a beaker?

1 of 2
Molar Heat of Fusion
Object:
In this experiment, you will determine the change in temperature of a mixture of warm
water and ice. From this data, the amount of heat absorbed by the ice can be determined
and ultimately, the molar heat of fusion of ice calculated.
Procedure:
1.
Obtain mass of styrofoam cup.
2.
Add 150 g of warm water (~ 30 °C).
3.
Obtain mass of cup plus water.
Stir the water with thermometer and determine the temperature to the nearest tenth
of a degree.
4.
Dry 1 ice cube with a paper towel to remove any water, and place the ice
immediately in the cup; do not splash any water from the cup.
5.
Stir quickly until all the ice is melted, then record the temperature to the nearest
tenth of a degree.
6.
7.
Determine the mass of the cup and water.

Evaporation of sweat requires energy and thus take excess heat away from the body. Some of the water that you drink may eventually be converted into sweat and evaporate. If you drink a 20-ounce bottle of water that had been in the refrigerator at 3.8 C, how much heat is needed to convert all of that water into sweat and then to vapor? (Note: Your body temperature is 36.6 oc. For the purpose of solving this problem, assume that the thermal properties of sweat are the same as for water.)
