Question

State any two factor on which the increase in the volume of a metallic block will depends on hearing​

Answer 1

To find:

Any two factor on which the increase in the volume of a metallic block will depends on heating.

Solution:

Let considered a block of volume V_(0) being heated such that the change in temperature of the block is $\Delta\theta$

Now, let change in volume of the metallic block be $\Delta V$

$\boxed{ \therefore \: \Delta V = V_{0} \gamma \Delta \theta}$

• Here $\gamma$ is the coefficient of volume expansion.

So, final volume becomes:

$\therefore V = V_{0}+\Delta V$

$\boxed{=> V = V_{0}\bigg(1+\gamma\Delta\theta\bigg)}$

So, required factors upon which the change in volume depends are:

• Initial volume of block

• Volume expansion coefficient.

• Temperature change of block.
