The increase in length of a material due to temperature change can be calculated using the coefficient of linear expansion (α) of the material and the original length (L) of the material.
For copper,
α = 1.7 x 10^-5 /°C
L = 2 meters
ΔT = 150°C - 0°C = 150°C
Using the formula ΔL = α x L x ΔT,
ΔL = (1.7 x 10^-5 /°C) x 2 meters x 150°C
ΔL = 0.0051 meters or 5.1 mm (rounded to one decimal place)
Therefore, the increase in length of a 2m copper from 0°C to 150°C is approximately 5.1 mm.
