Thermal properties and temperature — practice question

A $100\,\text{g}$ sample of water at $100\,^{\circ}\text{C}$ is turned into steam while staying at $100\,^{\circ}\text{C}$. The specific latent heat of vaporisation of water is $2300\,\text{J g}^{-1}$. How much thermal energy does the water absorb?

  • A$23\,\text{J}$
  • B$230\,\text{J}$
  • C$230\,000\,\text{J}$
  • D$23\,000\,000\,\text{J}$
