Period _____
1. How much energy is required to change 72g of a substance from 15(C to 83(C?
(Cp = 0.263 J/g(C)
2. If 2630 J of energy is added to 46g of a substance with a specific heat capacity of 1.48 J/g(C,
what is its temperature change?
3. Calculate the energy needed to change the temperature of 2.5 kg of AlF3 by 15.0(C.
(Cp AlF3 = 0.987 J/g(C)
4. What mass of water cools from 87.0(C to 2.5(C if 14,300J of energy is released?

WS Heat Calculations #2 Name _____________________________
Period _____
1. 48.0g of a metal sample is heated to 110.0(C, then place in a calorimeter with 143g of water at
22.0(C. If the final temperature is 29.5(C, what is the specific heat capacity of the metal?
2. A calorimeter that contains 150 g of water at 23.5(C is used to measure the specific heat capacity of
a certain metal. If 295 g of the metal at 98.0(C is used and the final temperature ends at 30.5(C,
what is the specific heat capacity of the metal?
