A brass rod is 2m long at a certain temperature.
What is it's length for a temperature rise of 100 k, if the expansivity of brass in 1.8*10

You mean 1.8 * 10^-5 I think
change in length = length * 1.8 * 10^-5 * 100 = 2 * 1.8 *10^-3 = .0036 which is less than 1/4 of a centimeter
so 2 meters + that change
