Which of the following statement(s) is/are correct?

366352 A student takes 50 \(g\) wax (specific heat \(=0.6\,\, {k\,\,cal} / {kg}^{\circ} {C}\) ) and heats it till it boils. The graph between temperature and time is as follows. Find the heat supplied to the wax per minute.

366353 A metal piece weighing \(15\;g\) is heated to \(100^\circ C\) and then immersed in a mixture of ice and water. At the thermal equilibrium the volume of the mixture is found to be reduced by \(0.15\;c{m^3}\) with the temperature of mixture remaining constant. Find the specific heat of the metal. Given specific gravity of ice \(=0.92\), specific gravity of water at \(0^\circ C = 1.0\), latent heat of fusion of ice \( = 80\,cal - {g^{ - 1}}.\)
