Problem 32P
A certain amount of heat is transferred to 2 kg of aluminum, and the same amount of heat is transferred to 1 kg of ice. Referring to Table 16-2, (a) is the increase in temperature of the aluminum greater than, less than, or equal to the increase in temperature of the ice? (b) Choose the best explanation from among the following:
I. Twice the specific heat of aluminum is less than the specific heat of ice, and hence the aluminum has the greater temperature change.
II. The aluminum has the smaller temperature change since its mass is less than that of the ice.
III. The same heat will cause the same change in temperature.

ANSWER:
Step 1 of 3
The heat energy exchanged will be the same for each object, but the temperature change of each object is inversely proportional to its heat capacity .
