Detailed explanation-1: -Explanation: 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 between states by adding or removing thermal energy, also known as heat. Each state of matter is related to a specific amount of energy. Changing the state of matter by adding heat is known as melting or boiling, whereas changing the state of matter by removing heat is known as condensing or freezing.

Detailed explanation-3: -Adding energy (heating) atoms and molecules increases their motion, resulting in an increase in temperature. Removing energy (cooling) atoms and molecules decreases their motion, resulting in a decrease in temperature. Energy can be added or removed from a substance through a process called conduction.

Detailed explanation-4: -Changing states of matter occur when matter loses or absorbs energy. When a substance absorbs energy; the atoms and molecules move more rapidly and this increased kinetic energy pushes particles far enough that they change form. This energy is usually heat or thermal energy.
