Question

states of matter
name:
give the correct definition for the following changes in state of matter.
gas → liquid
solid → liquid
liquid → solid
liquid → gas
draw the behavior of the particles in each state.
solid liquid gas

Explanation:

1. Gas to Liquid: Condensation is the process where gas changes to liquid. For example, when water vapor (gas) cools and forms liquid water droplets on a cold surface.
2. Solid to Liquid: Melting is when a solid (like ice) turns into a liquid (water) due to an increase in temperature.
3. Liquid to Solid: Freezing is the reverse of melting. Liquid (e.g., water) turns into solid (ice) when the temperature drops below its freezing point.
4. Liquid to Gas: Evaporation (or vaporization) is when a liquid (such as water in a puddle) turns into gas (water vapor). This can happen at the surface of the liquid even below its boiling point.

For drawing particle behavior:

• Solid: Particles are closely packed in a fixed, orderly arrangement. They vibrate in place but don't move freely.
• Liquid: Particles are close together but can move past one another. There is no fixed shape, and they have some freedom of movement compared to solids.
• Gas: Particles are far apart and move freely in all directions. They have a lot of space between them and no fixed volume or shape.

Answer:

1. Gas to Liquid: Condensation
2. Solid to Liquid: Melting
3. Liquid to Solid: Freezing
4. Liquid to Gas: Evaporation (or Vaporization)
