Why is ice effective at cooling drinks?
a. The sensible heat loss of water
b. The heat capacity of water
c. The latent heat of fusion
d. The diffusion of heat energy
ANS: C
The latent heat of fusion allows ice to absorb large amounts of heat when it begins melting. Although
it is absorbing more heat, the temperature of the ice remains the same until all the ice has changed back
into liquid form. Information can be found in the section Water Has Unusual Thermal Characteristics
