Question

The change in volume per unit volume of a body is called.

Answer 1

Answer:

it is called as dilation

Answer 2

Change in volume per unit volume is called dialation 'e'.

Explanation:

The change in volume perunit volume is dialation which is donated by 'e'.

                         ⇒ e = $\frac{v_{2 } - v_{1} }{v_{1} }$

          where, '$v_{1}$' is the initial state of volume.

                       and '$v_{2}$' is the final state of volume.

According to above, dialation which is denoted by 'e' is the ratio of difference of final state of volume '$v_{2}$' and initial state of volume '$v_{1}$' to the initial state of volume '$v_{1}$'.

Volume may be in cubic metres, cubic centimetres or in cubic milimeters etc.
