The coefficient of volumetric expansion of copper is 1.1 × 10-^5/°C. If the temperature of 3.5 m^3 of copper increases by 50°C, what is the increase in the volume of copper?

Answer 1

1.1 x 10^-5/^oC. For a temperature change of 50^oC, 1.1 x 50 = 55.0 x 10^-5/50^oC = 5.5 x 10^-4/50^oC.

When 3.5 m³ of copper heats up by 50^oC, the volumetric expansion is 3.5 x 5.5 = 19.25 x 10^-4 m³

= 1.9 x 10^-3 m³ = 0.0019 m³.
