Question 11

An electric resistance heater warms a metal die of mass 0.40 kg. The heater has a power of 120 W and operates for 300 s. During the heating interval, energy transferred from the die is recorded below.

Destination of transferred energyEnergy transferred
Press frame3000 J
Surrounding air5000 J

The specific heat capacity of the metal is 450 J kg−1 ∘C−1450\ \mathrm{J\,kg^{-1}\,{}^\circ C^{-1}}450 Jkg−1∘C−1.

Calculate the temperature rise of the metal die.
