P7 Solve problems involving expansion.
Task 1: A steam pipe has a length of 20 m at 20 degrees C. If the coefficient of linear expansion is 0.000012 /K. How much expansion will have to be allowed for when the steam increases the temperature of the pipe to 300°C?
Task 2: A copper sphere has a diameter of 40 mm at 0 degrees C. If the coefficient of linear expansion is 0.000017 /K, by how much will its volume increase when the temperature is raised to 100 degrees C?
The volume of a sphere is given by V=4/3 pi r^3
