Figure 1 shows a small travel kettle used to heat water.

An illustration of a compact travel kettle sitting on a power base, plugged into a mains socket. Inside the kettle, the water level is indicated, with the heating element located at the base of the chamber.

The kettle contains 0.40 kg of water.

Calculate the thermal energy needed to raise the temperature of the water by 75 °C.

Specific heat capacity of water = 4200 J/kg °C

Use the equation:

ΔE=m×c×Δθ \Delta E = m \times c \times \Delta\theta ΔE=m×c×Δθ
