Question

The coefficient of linear expansion of
to brass is 1.8x10-5c-! What do you
mean by
by this ?​

Answer 1

Explanation:

It means that for every degree (1°C) rise in temperature, Brass will expand linearly by 1.8× 10^-5

Answer 2

This means 1cm of a brass rod expands linearly by 1.2×10^-5 cm for 1° rise in temperature.
