If a temperature of a 2.00m long copper is raised from 15 c to 25 c . Find the change in length if a=1.7*10^-5

Answer 1

The change in length is 0.34 m.

The formula for calculating the change in length due to a change in temperature is:

ΔL = L * α * ΔT

Where L is the length of the copper, α is the coefficient of thermal expansion, and ΔT is the change in temperature.

In this case, L = 2.00 m, α = 1.7 * 10^-5, and ΔT = 10°C.

Plugging these values into the formula, we get:

ΔL = 2.00 m * 1.7 * 10^-5 * 10°C = 0.34 m
