Phase Changes of Matter

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

• Condensation

• Evaporation

• Sublimation

• Precipitation

What happens to the particles in a solid during melting?

• The particles lose energy and become more compact.

• The particles gain energy, move apart, and transition into a liquid state.

• The particles remain stationary and do not change.

• The particles gain energy and form a gas state immediately.

What is deposition?

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

• The process where a solid changes into a liquid.

• The process where a liquid changes into a gas.

• The process where a gas changes into a liquid.

What is the melting point?

• The temperature at which a solid becomes a liquid.

• The temperature at which a liquid becomes a gas.

• The temperature at which a gas condenses into a liquid.

• The temperature at which a solid sublimates directly into a gas.

What is sublimation?

• A process where a liquid changes into a solid.

• A process where a solid changes directly into a gas without becoming a liquid first.

• A process where a gas changes into a liquid.

• A process where a solid changes into a liquid.

How do particles behave in a gas?

• Particles in a gas are tightly packed and vibrate in place.

• Particles in a gas are far apart, move freely, and have weak attractive forces.

• Particles in a gas are arranged in a fixed structure and do not move.

• Particles in a gas are close together and slide past one another.

What happens to the energy of particles during a phase change?

• Energy is absorbed or released, affecting the state of matter.

• Energy remains constant throughout the phase change.

• Energy is only released during a phase change.

• Energy is converted into mass during a phase change.

What is freezing?

• Freezing is the process where a liquid turns into a solid as it loses energy.

• Freezing is the process where a solid turns into a liquid as it gains energy.

• Freezing is the process where a gas turns into a liquid as it loses energy.

• Freezing is the process where a liquid turns into a gas as it gains energy.

What occurs during condensation?

• Gas particles gain energy and transition into a solid state.

• Gas particles lose energy and transition into a liquid state.

• Gas particles remain unchanged and stay in a gaseous state.

• Gas particles lose energy and transition into a plasma state.

What is a phase change?

• A transition of matter from one state to another, such as solid to liquid or liquid to gas.

• A process where matter remains in the same state but changes its appearance.

• A chemical reaction that alters the molecular structure of a substance.

• A phenomenon that occurs only at absolute zero temperature.
