9 Three different materials of identical mass are placed one at a time in a special freezer that can ex- tract energy from a material at a certain constant rate. During the cooling process, each material begins in the liquid state and ends in the solid state; Fig. 18-28 shows the tem- perature T versus time t. (a) For ma- terial 1, is the specific heat for the liquid state greater than or less than that for the solid state? Rank the materials according to (b) freezing- point temperature, (c) specific heat in the liquid state, (d) specific heat in the solid state, and (e) heat of fusion, all greatest first.

A cheese ripening room which, has a total surface area of A = 25.0m2, has to ensure that the inside temperature does not exceed 11.0°C at all times. If the maximum outside temperature is 35.0°C and the cheese ripening room has an air conditioner which provides 125 kW of cooling, calculate the how thi ck the wooden walls would need to bein mm, in order to ensure the inside temperature do es not go above 11.0°C. Assume that the thermal W conductivity, k of wood is 0.0800 Assume that the entire cheese ripening room is m.C made of wood (including ceiling and floor) and ignore any losses through the door as it remains closed most of the time and is well sealed.

An automobile has a mass of 1 500 kg, and its aluminum brakes have an overall mass of 6.00 kg. (a) Assuming all the internal energy transformed by friction when the car stops is deposited in the brakes and neglecting energy transfer, how many times could the car be braked to rest starting from 25.0 m/s before the brakes would begin to melt? (Assume an initial temperature of 20.0°C.) (b) Identify some effects that are neglected in part (a), but are likely to be important in a more realistic assessment of the temperature increase of the brakes.
