Question

what do you understand by linear expansion

Answer 1

Explanation:

Linear expansion means change in one dimension (length) as opposed to change in volume (volumetric expansion). To a first approximation, the change in length measurements of an object due to thermal expansion is related to temperature change by a coefficient of linear thermal expansion (CLTE).

Answer 2

Answer:

linear expansion means in which the temperature of a linear things increase and it's lenths also increase and when the the temperature is decrease in sarrounded then it will shrink. this is known as linear expansion
