A laboratory beaker contains 0.650 kg of water at an initial temperature of 18.0 ∘C18.0\text{ }^\circ\text{C}18.0 ∘C.
An electrical immersion heater is used to heat the water to a final temperature of 78.0 ∘C78.0\text{ }^\circ\text{C}78.0 ∘C.
The specific heat capacity of water is 4200 J/kg ∘C4200\text{ J/kg }^\circ\text{C}4200 J/kg ∘C.
Calculate the thermal energy supplied to the water. Give your answer to an appropriate number of significant figures.
