Question $4.$ At $-10C,$ a $50g$ cube$-$shaped piece of ice is placed in a glass with $200ml$ of water at $28C$ it has been discarded. Calculate the temperature reached by the water after the ice has completely melted. During the process of melting ice the amount of heat transfer from the dental medium to the water by exceeding the glass wall is $2\mathrm{.}5kJ.$ The secret heat of melting ice $335$ the specific heat of $k\frac{j}{k}g$ and water is $1\mathrm{.}93k\frac{j}{k}gC.$ The specific heat of water is $4\mathrm{.}186k\frac{j}{}C.$
