Answer:

the change in length of the copper bar is 1.26 x 10^-3 meters (or 1.26 millimeters).

Step-by-step explanation:

The change in length of a copper bar can be calculated using the formula:

ΔL = L₀αΔT

where:

ΔL = change in length

L₀ = original length of the copper bar (1.5 m)

α = coefficient of linear expansion for copper (16.8 x 10^-6 K^-1)

ΔT = change in temperature (353 K - 303 K = 50 K)

Plugging in the values, we get:

ΔL = (1.5 m)(16.8 x 10^-6 K^-1)(50 K)

ΔL = 1.26 x 10^-3 m
