The coefficient of expansion of a certain steel is 0.000012 per °C. The coefficient of volume expansion, in (°C) –1, is:

1 answer

The coefficient of volume expansion, (β), is related to the linear coefficient of expansion, (α), as follows:

β = 3α

Therefore, the coefficient of volume expansion of the steel is:

β = 3(0.000012) per °C

β = 0.000036 per °C

Expressed in (°C) –1, the coefficient of volume expansion is:

β = 1/0.000036 (°C) –1

β ≈ 27,778 (°C) –1
