A $50$ g cube of ice at $-10\backslash$deg C was thrown into a glass containing $200$ ml of water at $28\backslash$deg C$.$ Calculate the temperature the water reaches after the ice has completely melted. During the melting process of ice, the amount of heat transfer from the external environment to the water through the glass wall is $2\mathrm{.}5$ kJ$.$ The latent heat of melting of ice is $335$ kJ$/$kg and the specific heat of water is $1\mathrm{.}93$ kJ$/$kg C$.$ The specific heat of water is $4\mathrm{.}186$ kj$/$C$.$
