Energy = mass ×specific heat capacity×change in temperature'

In this case, the mass of water is 50 kg, the specific heat capacity of water is 4184J/kg

the change in temperature is 80-45= 35 degrees celcius

Therefore, heat energy

           = 50 ×35 ×4184=7322000 Joules

But 1kJ =1000 Joules

therefore, the energy needed will be 7322 kJ
