Question

24. Give reason for the
following :-
a.Gas expand more than
liquid and solid.​

Answer 1

Answer:

Yes

Explanation:

It is so because the molecules of gas are freely movable so that's why they expand more than solid

Answer 2

Answer:

Gases expand more than liquids and solids:because the molecules of gases are seperated from one another by wide spaces. When gas is heated (heat is a form of energy) its molecules be

Explanation

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. The expansion in area is called area expansion. The expansion in volume is called volume expansion. Coefficient of thermal expansion measures the fractional change in size due to small change in temperature.
