Specific Heat Capacity
Tip: Remember the formulas? Know how to use them! :)
1. What amount of heat is produced when 64.8 grams of water goes from
2.2℃ to 12.4℃? The specific heat capacity of water is 4.186 J/℃g
2. How much heat is needed to raise a 0.30 g piece of aluminum from 30℃ to
150℃? (Specific heat capacity of aluminum: 0.9 J/℃g)
3. Calculate the temperature change when 4900 J of heat are added to 500 g of
copper. (Specific heat capacity of copper: 0.39 J/℃g)
4. How much heat is absorbed when 500.0 g of water , Cs = 4.184 J/℃g, goes
from 25.0℃ to 35.0℃?
5. How much heat is released when 150.0 g of iron cools from 525℃ to
100℃? (Cp = 0.44 J/g℃)
6. The temperature of a silver coin (Cs = 0.24 J/g℃) falls by 353℃ as it
releases 5,550 Joules of heat. What is the mass of the coin?
7. An aluminum can with a mass of 12.5 grams (Cs = .90 J/g℃) absorbs 245
Joules of heat. How much does the temperature rise?
