Exploring States of Matter

What are the three main states of matter?

• plasma, vapor, foam

• solid, liquid, plasma

• solid, liquid, gas

• gas, liquid, crystal

Define solid, liquid, and gas.

• Gas: fixed shape, no fixed volume

• Solid: no definite shape, no definite volume

• Solid: fixed shape and volume; Liquid: fixed volume, shape of container; Gas: neither fixed shape nor volume.

• Liquid: fixed shape and volume; Gas: fixed volume, shape of container

What happens to the particles in a solid?

• Particles in a solid move freely and are widely spaced apart.

• Particles in a solid are in constant motion and can change shape easily.

• Particles in a solid vibrate in fixed positions and are closely packed together.

• Particles in a solid are randomly arranged and have high energy.

How do particles behave in a liquid?

• Particles in a liquid are closely packed, can move past each other, and allow the liquid to flow.

• Particles in a liquid are fixed in place and cannot flow.

• Particles in a liquid behave like gas particles, expanding to fill the container.

• Particles in a liquid are widely spaced and do not move.

What is the characteristic of gas particles?

• Gas particles move in a straight line without any collisions.

• Gas particles have a fixed shape and volume.

• Gas particles are stationary and close together.

• Gas particles are in constant random motion and are far apart from each other.

What is melting?

• Melting is the process of freezing a liquid into a solid.

• Melting is the compression of a gas into a liquid.

• Melting is the evaporation of a liquid into gas.

• Melting is the transition of a solid to a liquid due to heat.

What is freezing?

• Freezing is the process of boiling water.

• Freezing is the transition of a substance from a liquid to a solid state.

• Freezing occurs when a solid turns into a gas.

• Freezing is the evaporation of a liquid into the air.

What is evaporation?

• Evaporation is the process of solid turning into liquid.

• Evaporation is the process of gas turning into liquid.

• Evaporation is the process of liquid turning into solid.

• Evaporation is the process of liquid turning into vapor.

What is condensation?

• Condensation is the process of water vapor turning into liquid water.

• Condensation is the evaporation of water from a surface.

• Condensation is the process of liquid water turning into water vapor.

• Condensation is the freezing of water into ice.

What is sublimation?

• Sublimation is the transition of a substance from solid to gas without becoming liquid.

• Sublimation refers to the melting of a solid into a liquid.

• Sublimation is the evaporation of a liquid into a gas.

• Sublimation is the process of a gas turning into a solid.
