Use the formulas listed to solve the problems below.
Q= (m)(c)(∆T)
m= Q / (c∆T)
c=Q/ (m∆T)
∆T = Q/ (mc)
1. What mass object would raise in temperature from 20.0 ˚C to 35.0˚C when 55.000 J of energy are added and the specific
heat of the object is 1.25 J /g ˙C˚ ?
2. How many joules of heat must be transferred to a 420 g aluminum pizza pan to raise its temperature from 22 ˚C to 232 ˚C?
The specific heat of aluminum is 0.96 J /g ˙C˚.
3. As 315 g of hot milk cools in a mug, it transfers 31,000 J of heat to the environment. What is the temperature change of the milk
its specific heat is 3.9 J /g ˙C˚?
4. How much heat will be given off by 55 g of water as it cools from 87 ˚C to 25 ˚C? The specific heat of water is 4.18J /g ˙C˚.
5. What is the specific heat of a piece of glass that has a mass of 65 g and increases in temperature from 10 ˚C to 36 ˚C when it
absorbs 840 J of heat?
6. How much heat will be absorbed by 320 g of water when its temperature is raised from 21 ˚C to 56 ˚C ?
