Question

does cubical expansivity of a substance depend on the temperature of a substance?

Answer 1

Answer:

it is yes.

Explanation:Does cubical expansivity depend upon initial volume of solid? ... Because we know cubical expansivity is equal to rise in increase in volume per unit initial volume per unit rise in temperature, where ratio of increase in volume and initial volume is constant.

Answer 2

Yes, the cubical expansivity of a substance depend on the temperature of a substance.

Explanation:

When an object is heated, its volume gets increased. The increase in volume on heating is called cubical expansion. The relation between the increase in volume and temperature is given by :

$\dfrac{\Delta V}{V_o}=3\alpha \Delta T$

$V_o$ = real volume

$\Delta V$ = increase in volume

$\alpha$ = coefficient of cubical expansion

$\Delta T$ = change in temperature

So, the cubical expansivity of a substance depend on the temperature of a substance. Hence, this is the required solution.
