Calculating Specific Heat
Extra Practice Worksheet
Q = mc∆T, where Q = heat energy, m = mass, and ∆T = change in temp.
Remember, ∆T = (Tfinal – Tinitial). Show all work and proper units.
1. A 15.75-g piece of iron absorbs 1086.75 joules of heat energy, and its temperature
changes from 25°C to 175°C. Calculate the specific heat capacity of iron.
2. How many joules of heat are needed to raise the temperature of 10.0 g of aluminum from
22°C to 55°C, if the specific heat of aluminum is 0.90 J/g°C?
3. Calculate the specific heat capacity of a piece of wood if 1500.0 g of the wood absorbs
67,500 joules of heat, and its temperature changes from 32°C to 57°C.
