Calculate the total heat required to raise the temperature of in an aluminium kettle of mass 0.50 kg from 30 o C to 100 o C. Given information; Specific heat capacity of water = 4200 J kg -1 o C -1 Specific heat capacity of aluminium 880 J kg -1 o C -1 Mass of water = 2.0 kg Mass of kettle = 0.50 kg ΔΘ = 70

Q = mc(ΔΘ)+ mc(ΔΘ) = 2 x 4200 x 70 + 0.50 x 880 x 70 = 588000 + 30800 = 618800
