State Changes

What is the term for the change from gas to solid?

• Condensation

• Sublimation

• Deposition

• Evaporation

What happens to the temperature of a substance during melting?

• The temperature increases steadily until the solid melts completely.

• The temperature decreases until the solid is fully melted.

• The temperature remains constant until the entire solid has melted.

• The temperature fluctuates during the melting process.

What occurs during vaporization?

• A liquid absorbs thermal energy and changes into a gas.

• A solid loses thermal energy and becomes a liquid.

• A gas condenses into a liquid by releasing thermal energy.

• A liquid freezes and becomes a solid.

What is the process called when a solid turns into a liquid?

• Freezing

• Condensation

• Melting

• Evaporation

What is sublimation?

• The process where a solid turns directly into a gas without becoming a liquid.

• The process where a liquid turns into a solid.

• The process where a gas turns into a liquid.

• The process where a solid turns into a liquid.

What happens to the particles of a substance when it cools down?

• They speed up and move further apart.

• They slow down and move closer together.

• They remain at the same speed and distance.

• They change into a gas.

What is the effect of removing thermal energy from a gas?

• It can cause the gas to condense into a liquid.

• It increases the gas's temperature.

• It causes the gas to expand.

• It changes the gas into a solid.

What is the relationship between temperature and particle movement?

• As temperature increases, particle movement decreases.

• As temperature increases, particle movement remains constant.

• As temperature increases, particle movement increases.

• As temperature decreases, particle movement increases.

What is thermal energy?

• The energy that comes from the temperature of matter.

• The energy stored in chemical bonds.

• The energy associated with the motion of particles in a solid.

• The energy released during nuclear reactions.

What is the process called when a liquid turns into a solid?

• Evaporation
