Changes in States of Matter

What is meant by the term 'change of state'?

• Change of state refers to the change in color of a substance.

• Change of state is the transformation of a substance between solid, liquid, and gas.

• Change of state is the process of mixing two different substances.

• Change of state describes the increase in temperature of a substance.

Name the three main states of matter.

• ice, mist, smoke

• solid, liquid, gas

• rock, water, steam

• plasma, vapor, foam

What happens to ice when it melts?

• Ice becomes solid again after melting.

• Ice turns into steam when it melts.

• Ice transforms into gas when it melts.

• Ice turns into liquid water when it melts.

What is the process called when water turns into steam?

• Condensation

• Sublimation

• Freezing

• Vaporization

Describe what happens to a solid when it is heated.

• A solid expands and may eventually melt into a liquid when heated.

• A solid contracts and becomes denser when heated.

• A solid turns into gas immediately upon heating.

• A solid remains unchanged regardless of temperature.

What is condensation?

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

• Condensation is the freezing of water into ice.

• Condensation is the evaporation of water from a surface.

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

Give an example of a substance that can change from solid to liquid.

• Ice

• Steam

• Water

• Rock

What is the difference between evaporation and boiling?

• Boiling happens at any temperature and only at the surface.

• Evaporation occurs only at high temperatures and throughout the liquid.

• Evaporation occurs at any temperature and only at the surface, while boiling occurs at a specific temperature throughout the liquid.

• Evaporation and boiling are the same process occurring at different speeds.

How does temperature affect the state of matter?

• Temperature changes the color of matter but not its state.

• Temperature only affects gases, not solids or liquids.

• Temperature has no effect on the state of matter.

• Temperature influences the state of matter by changing the energy and movement of particles, leading to phase transitions.

What is sublimation?

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

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

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

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