3 solid
4 liquid
5 gas
6 freezing
7 sublimation
8 evaporation
9 deposition

Explanation:

To provide definitions for these terms (related to matter and its states/phase changes), here are the key explanations:

1. Matter

Definition: Anything that has mass and occupies space (has volume). It is made up of particles (atoms, molecules, ions) and exists in different physical states (solid, liquid, gas) or can undergo chemical changes.

2. Mass

Definition: A measure of the amount of matter contained in an object. It is a scalar quantity (has magnitude, no direction) and is typically measured in kilograms (kg), grams (g), etc. Unlike weight, mass is constant regardless of location (e.g., an object’s mass on Earth is the same as on the Moon, but its weight differs due to gravity).

3. Solid

Definition: A state of matter with a definite shape and volume. In solids, particles (atoms/molecules) are closely packed in a fixed, orderly arrangement (lattice structure) and vibrate in place. They have strong intermolecular forces, so they resist deformation (e.g., a rock, ice, metal).

4. Liquid

Definition: A state of matter with a definite volume but no fixed shape (it takes the shape of its container). Particles in a liquid are close together but can move past one another (weaker intermolecular forces than solids, stronger than gases). Liquids can flow and exhibit surface tension (e.g., water, oil, alcohol).

5. Gas

Definition: A state of matter with no definite shape or volume (it expands to fill its container). Gas particles are far apart, move freely and rapidly (with high kinetic energy), and have very weak intermolecular forces. Gases are compressible (e.g., air, oxygen, carbon dioxide).

6. Freezing

Definition: The physical process (phase change) where a liquid turns into a solid. It is the reverse of melting. For a substance to freeze, it must lose heat (energy) and reach its freezing point (the temperature at which liquid and solid coexist in equilibrium, e.g., water freezes at 0°C to form ice).

7. Sublimation

Definition: The phase change where a solid directly turns into a gas without passing through the liquid state. Energy (heat) is absorbed by the solid, causing particles to break free from the solid structure and enter the gaseous state (e.g., dry ice (solid CO₂) sublimes into CO₂ gas; mothballs (naphthalene) sublime over time).

8. Evaporation

Definition: The process of a liquid turning into a gas (vapor) at temperatures below its boiling point. It occurs at the liquid’s surface, where molecules with enough kinetic energy escape into the air. Evaporation is a cooling process (e.g., water evaporating from a puddle, sweat evaporating from skin to cool the body).

9. Deposition

Definition: The phase change where a gas directly turns into a solid without passing through the liquid state. It is the reverse of sublimation. Energy (heat) is released by the gas as particles slow down and form a solid structure (e.g., frost forming on cold surfaces when water vapor in the air deposits into ice crystals; snow formation in clouds).
