Detailed Solution

The given statement is false.
Heat energy is a form of thermal energy which increases the temperature of any substance by increasing the movement of molecules in it. Suppose heat energy is provided to different substances due to the movement of the molecules of the substance. In that case, the force of attraction between the molecules decreases and the expansion of the substance may occur. The expansion will be different for different substances, the expansion of gas will be highest as the molecules have significantly less force of attraction and minimum in the solid as the force of attraction will be highest in solids.
The correct statement would be that the expansion of every substance is different if the temperature increase is of the same amount for every substance.
