Amplify Phase Change Assessment Review

How does temperature affect phase changes?

• Temperature changes can provide or remove energy, causing substances to change from one phase to another.

• Temperature has no effect on phase changes.

• Temperature only affects the speed of molecules, not phase changes.

• Phase changes occur only at absolute zero temperature.

What is a phase change?

• A process where matter changes from one state to another due to energy changes.

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

• A phenomenon that occurs only at absolute zero temperature.

• A method of separating mixtures based on particle size.

What is melting?

• Melting is the phase change from solid to liquid that occurs when a substance absorbs heat.

• Melting is the process of a liquid turning into a gas.

• Melting is the transition of a solid to a gas without becoming liquid.

• Melting is the process of a solid becoming more solid due to pressure.

What is the boiling point?

• The temperature at which a liquid's vapor pressure equals the external pressure, causing it to change to gas.

• The temperature at which a liquid freezes into a solid.

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

• The temperature at which a substance undergoes a chemical reaction.

What is freezing?

• Freezing is the phase change from liquid to solid that occurs when a substance loses heat.

• Freezing is the process of heating a solid until it becomes a liquid.

• Freezing is the transformation of gas into liquid when cooled.

• Freezing is the process of evaporating a liquid into gas.

What happens to molecules during a liquid phase?

• Molecules are far apart and do not move.

• Molecules are close together but can move around each other, allowing the liquid to take the shape of its container.

• Molecules are tightly packed and vibrate in place.

• Molecules are in a fixed position and cannot move.

What is sublimation?

• A phase change from liquid to gas

• A phase change from solid to gas without passing through the liquid phase

• A process of freezing a substance

• A chemical reaction that produces gas

Why do different substances have different freezing points?

• Different substances have different freezing points due to variations in molecular structure and the strength of molecular attractions.

• All substances freeze at the same temperature regardless of their properties.

• The freezing point of a substance is solely determined by its mass.

• Different substances have different freezing points because of their color.
