Problem 12: Several ice cubes (ρ_i = 0.9167 g/cm³) of total volume V_i = 275 cm³ and temperature 273.15 K (0.000 °C) are put into a thermos containing V_t = 610 cm³ of tea at a temperature of 313.15 K, completely filling the thermos. The lid is then put on the thermos to close it. Assume that the density and the specific heat of the tea is the same as it is for fresh water (ρ_w = 1.00 g/cm³, c = 4186 J/kgK).

33% Part (a) Calculate the amount of heat energy Q_m in J needed to melt the ice cubes (L_f = 334 kJ/kg).
33% Part (b) Calculate the equilibrium temperature T_E in K of the final mixture of tea and water.

33% Part (c) Calculate the magnitude of the total heat transferred Q_T in J from the tea to the ice cubes.
