Question 12

In a laboratory test of a thermal management system, a researcher vaporises 75 g of ultra-pure liquid water at its boiling point.

The specific latent heat of vaporisation of water is 2.26 × 10⁶ J/kg.

Calculate the thermal energy required to vaporise this mass of water. Use the correct equation from the Physics Equation Sheet.
