Specific Heat Calculations Worksheet
(Show all work needed to solve the following problems)
Name:
1. Calculate the joules of heat needed to warm 53.87 g of ice at -40oC to ice at 0oC.
Specific Heat of Ice = 2.06 J/g*K
2. Calculate the joules of heat needed to cool 159 g of water at 100oC to water at 65oC.
3. Calculate the joules of heat needed to raise the temperature of 45.78 g of water from 25oC
to 95oC.
4. A student made a copper bracelet by hammering a small copper bar into the desired
shape. The bracelet has a mass of 30.1 grams and was at a temperature of 21°C in the
classroom. After the student wore the bracelet, the bracelet reached a temperature of
33°C. Later, the student removed the bracelet and placed it on a desk at home, where it
cooled from 33°C to 19°C. The specific heat capacity of copper is 0.385 J/g•K. Calculate
the amount of heat the bracelet lost while on the desk.
5. Calculate the joules of heat that must be removed to cool 30 g of water from 60oC to
25oC.
6. A sample of water has a mass of 22.59 grams and is at 45oC. How much heat must be
added to increase the temperature to 100oC?
