Give reason substance expand on heating |
|
Answer» When a substance is heated, its molecular movement increases. Due to this, the average DISTANCE between the molecules ALSO increases, thereby increasing the volume of the substance, i.e., expanding the substance.Explanation -:All THREE states of matter (solid, liquid and gas) expand when heated. ... Heat causes the molecules to move FASTER, (heat energy is converted to kinetic energy ) which means that the volume of a gas increases more than the volume of a solid or liquid. |
