Thermal energy is transferred to water in a beaker at a rate of $3000\,\text{W}$. The water is already at its boiling point. The specific latent heat of vaporisation of water is $2260\,\text{J g}^{-1}$. How long does it take for $250\,\text{g}$ of the water to vaporise?
- A$12\,\text{s}$
- B$188\,\text{s}$
- C$332\,\text{s}$
- D$750\,\text{s}$
