| 1. How many grams of water would require 2.20
x 104 calories of heat to raise its temperature from 34.0 oC to
100.0 oC? (Remember the specific heat of water is 1.00 cal/g x oC)
|
| 2. 8750 J of heat are applied to a piece of aluminum, causing a 56 oC increase in its temperature. The specific heat of
aluminum is 0.9025 J/g x oC. What is the mass of the aluminum?
|
| 3. Find the mass of a sample of water if its
temperature dropped 24.8 oC when it lost 870 J of heat. (remember that
4.18 J = 1.00 cal)
