Write a hypothesis about how the height of the cylinder affects the temperature of the water. use the "if . . then . . because . .” format and be sure to answer the lesson question: "how is potential energy converted to thermal energy in a system? ”

If the mass of the cylinder increases, the temperature of the water increases, because a greater mass means the cylinder has more potential energy that can be converted to thermal energy, increasing the temperature of the water.

if you already have the answer to (a), then just work out how many periods there are in 1 minute, and that's the answer to (c).
