A mass of 0.063 kg of water was turned into steam.
The specific latent heat of vaporisation of water is 2 260 000 J/kg.
Calculate the thermal energy transferred to the water to turn it into steam.
Use the equation:
thermal energy for a change of state = mass × specific latent heat

Specific latent heat of vaporisation is the energy required to change the state of 1 kg of a substance from liquid to gas without any change in temperature. The equation to calculate the total thermal energy (E) needed for a change of state is: E = m × L Where: - m is the mass of the substance (0.063 kg) - L is the specific latent heat of vaporisation (2 260 000 J/kg) Substituting the values: E = 0.063 × 2 260 000 E = 142 380 J
