A heat brick is heated and then allowed to cool. In 2 hours, the brick transfers 82000J of energy to the surroundings.
The mass of the brick is 2kg.
The specific heat capacity of the brick is 600 J/kg°C.
The brick is heated to an initial temperature of 150°C.
Calculate the temperature of the brick after 2 hours.
