Question

Differentiate between linear expansion and superficial expansion

Answer 1

Linear expansion means change in one dimension (length) as opposed to change in volume (volumetric expansion). ... This equation works well as long as the linear-expansion coefficient does not change much over the change in temperature , and the fractional change in length is small .

Answer 2

Explanation:

$liquid \: and \: gases \: show \: only \: \\ cubical \: expansion \: but \: no \: \\ linear \: or \: superficial \: \\ expansion \: beause \: they \: do \\ not \: hav \: definite \: shape \: and \\ size \\ \\ hope \: it \: hlps \: uh$
