Question

Volume expension cofficient is lowest in which substance

Answer 1

Answer:

Explanation:

COEFFICIENT OF VOLUME EXPANSION: A figure, constant for any particular type of material, used in calculating the amount by which the volume of that material will change as a result of temperature change. For any given substance, the coefficient of volume expansion is typically a number expressed in terms of 10−4/°C.

Answer 2

Answer:

For a solid, we can ignore the effects of pressure on the material, and the volumetric thermal expansion coefficient can be written: where is the volume of the material, and is the rate of change of that volume with temperature. This means that the volume of a material changes by some fixed fractional amount.
