Two metal rods, one silver and the other copper, are both attached to a steam chamber as shown in the figure, with a temperature of 100°C, at one end, and an ice water bath, with a temperature of 0°C, at the other. The rods are 5.0 cm long and have a square cross-section, 2.0 cm on a side. When steady state has been reached, how much heat flows through the two rods in 1.0 min? The thermal conductivity of silver is 417 W/(m · K), and that of copper is 395 W/(mK). No heat is exchanged between the rods and the surroundings, except at their ends.

Consider a 3-m-high, 6-m-wide, and 0.3-m-thick brick wall whose thermal conductivity is k = 0.8 W/m K. On a certain day, the temperatures of the inner and the outer surfaces of the wall are measured to be 14°C and 2°C, respectively. Determine the rate of heat loss through the wall on that day.
Two water bottles X and Y have the same mass (m) and very similar size and shape but are made from different materials (Mx and My respectively) at room temperature. The same amount of boiling water is put into X and Y, and then both bottles are closed with screw caps. After 5 minutes, the temperature of water in bottle X is higher than the water in bottle Y. We may then conclude that (with an explanation): (a) Mx has higher specific heat and the water in X has lower internal energy. (b) Mx has lower specific heat and the water in Y has higher internal energy. (c) My has lower specific heat but the water in X and Y have the same internal energy. (d) My has higher specific heat but the water in X has higher internal energy. (e) My and My have the same specific heat and the water in X and Y have the same internal energy.
Suppose you have 2.5kg of steam at 100 degrees celcius occupying 6.5 meters cubed at a pressure of 1.013 x 10^5 Pa. When the steam condenses to water at 100 degrees celcius it occupies a volume of 0.55 meters cubed. If the latent heat of vaporization of water is 2.26 x 10^6 J/kg, what was the change in the water's internal energy?

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.
