A glass containing 250 cm3 of water at 12 ∘C^{\circ}\mathrm{C} is cooled by inserting an ice cube of mass 50 g at a temperature of −18 ∘C-18\,^{\circ}\mathrm{C}. - specific heat capacity of ice =2100 J kg−1 ∘C−1= 2100\,\text{J}\,\text{kg}^{-1}\,^{\circ}\text{C}^{-1} - specific latent heat of fusion of ice =3.3×105 J kg−1= 3.3 \times 10^5\,\text{J}\,\text{kg}^{-1} Calculate the final temperature of the glass of water.
