A 2.50-m length of copper pipe extends directly from a hot-water heater in a basement to a faucet on the first floor of a house. If the faucet isn't fixed in place, how much will it rise when the pipe is heated from 16.5°C to 82.5°C. Ignore any increase in the size of the faucet itself or of the water heater.

If the coefficient of expansion of copper is .0000168/Deg. C
Then the change in length of the pipe is .0000168 x (82.5 -16.5Deg. C) x 2.5 m = 0.00272m = .1071inches

linear expansion is the the difference in length of a material, after being subjected to heat each material has a different coefficient of linear expansion, ie copper, steel, plastic etc themal expansion of fluid such as water when boiled expands simples

It won't rise at all. The expansion tank on the water heater would compensate for the expansion. They are required where I live because of the anti-backflow valves in the city water system.
