Question

44. Define linear expansivity and cubical expansivity.
​

Answer 1

Answer:

Your Answer is here:-

Explanation:

Linear expansion means change in one dimension (length) as opposed to change in volume (volumetric expansion). ... The area thermal expansion coefficient relates the change in a material's area dimensions to a change in temperature. It is the fractional change in area per degree of temperature change.

Answer 2

Answer:

The linear expansivity of asubstance is the fractional change in length of a sample of thesubstance per degree C change in temperature.

The increase in volume of a substance with a change in temperature or pressure is called cubical expansivity.
