heat capacity of the granite.
• Place the granite in boiling water for some time to ensure
that its temperature reaches 100 °C.
Remove the granite from the boiling water and immediately
place it in a beaker containing 0.10 kg water initially at 20 °C.
• Use a thermometer to observe the temperature of the water
until it stops rising - it can now be assumed that the granite
and water are at the same temperature.
•
The student finds that the water in the beaker reaches a
maximum temperature of 56 °C.
She assumes that the thermal energy lost by the stone is gained
by the water.
Given that the specific heat capacity of water is
4,200 J/kg°C, use the student's result to calculate the
specific heat capacity of granite.
