delta L / L = 0.000017 * 100 = 0.0017
delta L = 2 * 0.0017 = 0.0034 meters = 0.34 centimeters
Answer
Calculate the increase in length of a 2m copper that is hated from 9°c to150°c

We can use the formula below to calculate the increase in length of the copper rod:

ΔL = L * α * ΔT

Where:

ΔL = change in length
L = initial length of the copper rod (2m)
α = coefficient of linear expansion of copper (0.000017 / °C)
ΔT = change in temperature (150°C - 9°C = 141°C)

So,

ΔL = 2 * 0.000017 * 141
= 0.004794 meters
= 4.794 millimeters

Therefore, the increase in length of the copper rod is approximately 4.794 millimeters.

So,

= 0.0051 meters
= 5.1 millimeters

Therefore, the increase in length of the copper rod is approximately 5.1 millimeters.
