Heat and Temperature

Calculating specific heat capacity

What is the difference between heat and temperature?

Water has a specific heat capacity of 4200 J/kg/°C. A kettle is used to heat 0.80 kg water from 30°C to 100°C.
Calculate the energy change.

Glass has a specific heat capacity of 840 J/kg/°C. Calculate the energy required to increase the temperature of a 1.5 kg block of glass by 80°C.

The specific heat capacity of lead is 130 J/kg/°C.
A heater provides 8.0 kJ of energy when heating a block of lead from 20°C to 60°C. Calculate the mass of the lead block.

1. 0.65kg
2. 1.03kg
3. 1.54kg
4. 3.01kg

A kettle provides 8.40 kJ of energy to a 0.25 kg sample of water which has a specific heat capacity of 4200 J/kg/°C.
Calculate the increase in temperature of the water.

1. 0.13
2. 8.0
3. 16.0
4. 32.0

A 1.2 kg rock sample is heated using 14.0 kJ.


A 1.2 kg rock sample is heated using 14.0 kJ. The temperature of the sample increases from 21°C to 33°C.
Calculate the specific heat capacity of the rock.

1. 216 J/kg/°C
2. 353 J/kg/°C
3. 555 J/kg/°C
4. 972 J/kg/°C
