At a remote arctic research base, liquid water is obtained bymelting ice in a propane-fueled conversion tank. Propane has a heat ofcombustion of 25.6 MJ/L, and 30% of the released energy supplies heat tothe tank. Liquid water at 0°C is drawn off the tank at a rate of 500 mL/min,while a corresponding amount of ice at 0°C is continually inserted intothe tank from a hopper.

A piece of metal was at a temperature of 27oC when it was found to be emitting thermal radiation at a rate of 0.20 W (J/s). Then it was placed in a furnace and brought to a temperature of 927oC. What would be the rate of thermal radiation emitted by this object at this higher temperature? Assume no change in surface area or emissivity.
An automobile has a mass of 1,547 kg, and its aluminum brakes have an overall mass of 10.2 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 29.0 m/s before the brakes would begin to melt? (Assume an initial temperature of 20.0°C. Count only the number of times the car can come to a complete stop without the brakes melting in the process. The melting point of aluminum is 660°C.)

A dog loses a lot of heat by panting. The air rushing over the upper respiratory tract causes evaporation and thus heat loss. A dog typically pants pants at a rate of around 304 pants per minute. As a rough calculation, assume that one pant causes 0.0400 g of water to be evaporated from the respiratory tract. What is the rate of heat loss for the dog by panting? The heat of vaporization for water is 2256 kJ/kg.
