Six insulated containers hold 3,375 g of water at 24°C. A small copper cylinder is placed in each container; the masses and initial temperatures of the cylinders vary as given below. Rank the containers according to the maximum temperature of the water in each container after the cylinder is added, from largest to smallest. You may assume that the cylinder is completely submerged in the water. (Use only ">" or "=" symbols. Do not include any parentheses around the letters or symbols.)
m = 225 g; T = 30°C
m = 450 g; T = 60°C
m = 675 g; T = 90°C
m = 450 g; T = 15°C
m = 675 g; T = 30°C
m = 225 g; T = 60°C
Consider a cylindrical metal rod that stands on its base in a vertical orientation. The temperature increases uniformly. What happens to the pressure at the base of the rod as the rod expands? Does it increase, decrease, or remain unchanged? Explain your reasoning.
Answer this HOMEWORK question.
Imagine two cooking pots of the same dimensions, each containing a different amount of water at the same initial temperature, 100⁰C. The bottom of the first pot is made of steel, while the bottom of the second pot is made of aluminum. Both pots are placed on a hot surface having a temperature of 180 ⁰C. The water in the steel-bottomed pot boils away completely in 450 s. a) Roughly how much water boiled away from the steel pot, if the bottom has a surface a of 0.031 m2, and a thickness of 3 mm?b) How long would it take to boil away the same amount of water from the aluminum pot?

- An insulated container holds m = 5.23 kg of the solid form of a substance right at the melting temperature of 229.7 K (think "ice"). It is connected to an insulated container that contains the vapour form of the same substance (think "steam") in such a way that heat can transfer between the two containers, but not with the environment. The vapour is exactly at the vapourization temperature of 301.6 K, and the container has exactly enough vapour so that the moment the solid portion has finished melting, exactly all of the vapour has finished condensing. The latent heat of fusion of the substance is 46850 J/kg and the latent heat of vapourization of the substance is 73380 J/kg.
