A glass containing

250\,\text{cm}^3

of water at

12\,^{\circ}\mathrm{C}

is cooled by inserting an ice cube of mass

50\,\text{g}

at a temperature of

-18\,^{\circ}\mathrm{C}

. - Specific heat capacity of ice

=2100\,\text{J}\,\text{kg}^{-1}\,^{\circ}\text{C}^{-1}

- Specific latent heat of fusion of ice

=3.3\times10^5\,\text{J}\,\text{kg}^{-1}

Calculate the final temperature of the glass of water.
