Homework Statement
A 2.5 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 20.0°C to 86.5°C. The coefficient of linear expansion for copper is 16 multiplied by10-6 K-1. Ignore any increase in the size of the faucet itself or of the water heater.
