In the morning, a concrete statue of specific heat = 600 j/(kg k) has a temperature of 15°c. during the day, it sits in the sun and warms up to 40°c, gaining 90,000 j of thermal energy. what is its mass?
The equation we need to use is:
The following data is given:
Note that it is not necessary to convert the temperatures into Kelvin as the temperature difference is the same (
Rearrange for mass and sub. in values:
