A high-performance computer cooling loop uses liquid ammonia to absorb heat from a processor.

During a heavy processing load, 18.4 g18.4\text{ g}18.4 g of liquid ammonia at its boiling point is completely vaporised into gas.

The specific latent heat of vaporisation of ammonia is 1.37×106 J/kg1.37 \times 10^6\text{ J/kg}1.37×106 J/kg.

Calculate the energy transferred to vaporise this mass of ammonia. Use the equation: energy=mass×specific latent heat\text{energy} = \text{mass} \times \text{specific latent heat}energy=mass×specific latent heat
