Answer: The correct answer is liquid.
Explanation:
Liquid, gas and solid are the states of the matter.
Solid: In the solid, the inter molecular force of attraction is strongest. The particles are more tightly packed in this in comparison to liquid and gas. It has definite shape and volume. For example, iron.
Gas: In the solid, the inter molecular force of attraction is very less. The particles are not tightly packed in this in comparison to solid and liquid. For example, hydrogen gas.
Liquid: In the liquid, the inter molecular force of attraction is not very strong. The particles are loosely packed. It has no definite shape but has definite volume. For example, water.
Therefore, water is an example of a liquid.

- Something rusting
- photosynthesis
- metabolism/digestion
- Nuclear power [atoms are arranged differently]
- Smashing paper with two metal balls, burns paper
- Electricity in water, breaks H2O into H2 and O2

physical change is when there is only physical change occurring--and it can typically be undone easily,
whereas chemical change is when there is chemical change--which changes the chemical properties of something, which cannot be undone simply.
hope this helps!!
