a. Thermal expansion is maximum in
​

Answer 1

Answer:

In case of gases, when balloon is partially inflated in a cool room it expands to full size when put in warm water. This all is due to thermal expansion. So, increase in dimension of a body due to increase in temperature is thermal expansion. The expansion in length is called linear expansion.
