Question

The volume of a block of metal changes by 0.12% when it is heated through 20°C. What is the co-efficient of linear expansion of the heat?

Answer 1

Answer:

If the volume of a block of metal changes by 0.12%, when it is heated through 20∘C, then the coefficient of linear expansion is then. 4×10−5 per ∘C. 2×10−5 per ∘C.
