Question

differentiate between cubical and linear expansion

Answer 1

$<b>Difference 1</b>$
In the linear expansion, object expands along one dimension only. ( Expands in only one direction)

And in cubical expansion object expands along three dimensions. ( Expands in all directions)

$<b>Difference 2</b>$
Shape of an object changes in linear expansion

The shape of an object does not change in the cubical expansion.

$<b>Difference 3</b>$
Increased volume will not be proportional to the initial volume in the linear expansion.

Increased volume will be proportional to the initial volume in the cubicle expansion.
