Exploring Phase Changes

What is a phase change?

• A phase change is the transition of a substance between different states of matter.

• A phase change refers to the color change of a substance.

• A phase change is a chemical reaction.

• A phase change is the process of mixing two substances.

Name the three common states of matter.

• solid, liquid, gas

• ice, mist, smoke

• plasma, vapor, foam

• rock, water, steam

What is melting?

• Melting is the condensation of gas into a liquid.

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

• Melting is the evaporation of a liquid into gas.

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

What is freezing?

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

• Freezing is when a substance evaporates into the air.

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

• Freezing is the change of a gas into a liquid state.

Define evaporation.

• Evaporation is the process of solid turning into liquid.

• Evaporation is the process of liquid turning into vapor.

• Evaporation is the process of gas turning into liquid.

• Evaporation is the process of liquid turning into solid.

What is condensation?

• Condensation is the evaporation of liquid water into vapor.

• Condensation is the process of ice melting into water.

• Condensation is the process of water turning into steam.

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

What is sublimation?

• The transition of a substance from gas to liquid.

• The process of a gas turning into a solid directly.

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

• The change of a liquid into a solid without passing through a gas phase.

What is deposition?

• Deposition is the process of breaking down rocks into smaller pieces.

• Deposition is the process of evaporating water from a surface.

• Deposition refers to the movement of materials from one location to another.

• Deposition is the accumulation of materials such as sediments and rocks in a new location.

How does temperature affect phase changes?

• Temperature influences phase changes by altering the energy of particles, facilitating transitions between solid, liquid, and gas states.

• Phase changes occur only at absolute zero temperature.

• Temperature has no effect on phase changes.

• Temperature only affects the color of substances during phase changes.

Can phase changes occur without temperature change?

• Phase changes always require a temperature change.

• Phase changes can only occur at absolute zero.

• Phase changes are independent of pressure changes.

• Yes, phase changes can occur without temperature change.
