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
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
