A metal plate has a mass of 0.75 kg and a specific heat capacity of 900 J kg−1 ∘C−1900\ \mathrm{J\,kg^{-1}\,{}^\circ C^{-1}}900 Jkg−1∘C−1. An electric heater transfers energy to the plate at a power of 180 W for 150 s. Assume that all the energy transferred by the heater is absorbed by the plate.
Calculate the temperature rise of the plate.
