The diagram illustrates the apparatus set up to determine the specific latent heat of vaporisation of water. Once the water starts boiling, $110\text{ g}$ of water changes into steam in $120\text{ s}$. From these data, what is the value of the specific latent heat of vaporisation of water?
- A$1.8\,\text{J kg}^{-1}$
- B$1800\,\text{J kg}^{-1}$
- C$2200\,\text{J kg}^{-1}$
- D$2\,200\,000\,\text{J kg}^{-1}$
