Question

A heater of power, P watts, supplies thermal energy to 100g of ice at -8 °C until

it fully converts to steam at 100 °C. This heating process took 5.5 minutes.

Calculate the value of P.

Specific heat capacity of ice = 2030 J/kg K

Latent heat of fusion of water = 3.36 * 10⁵

J/kg

Specific heat capacity of water = 4200 J/kg K

Latent heat of vaporisation of water = 2.26 * 10⁶

J/kg​
