Question

How can you say different liquids have
different rates of expansion for the same rise
in temperature?​

Answer 1

Explanation:

Different liquids have different rates of expansion. I think we can fairly say that (most) substances expand when heating because they vibrate more, because they have more kinetic energy, so there's a pushing force between molecules. For almost the same reason, gasses expand.

Answer 2

Different liquids have different rates of expansion for the same rise in temperature because all liquids have different densities and according to the density they expand.
