SSC MTS EXAM

Detailed explanation-1: -Adding or removing energy from matter causes a physical change as matter moves from one state to another. For example, adding thermal energy (heat) to liquid water causes it to become steam or vapor (a gas). And removing energy from liquid water causes it to become ice (a solid).

Detailed explanation-2: -Matter can change from one state to another by either heating or cooling. For example, if ice is heated it changes to water and on heating water it changes to steam. This happens because the heat supplied breaks the intermolecular forces of attraction between the molecules.

Detailed explanation-3: -Yes, it can definitely change its shape, size and volume. For example: water turns into ice upon freezing, here the form of water converts from the liquid state into the solid state; the matter itself does not change but it transforms its shape.
