Solids, Liquids, Gases

Front

What is the shape and volume of a liquid?

Back

A liquid has no definite shape and has a definite volume.

Front

Describe the arrangement of molecules in a liquid state of matter.

Back

In a liquid, molecules slide past each other but stay close together, and they do not form a regular pattern.

Front

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

Back

The process is called evaporation.

Front

What is surface tension in liquids?

Back

Surface tension is an inward force or pull among the molecules in a liquid that brings the molecules on the surface closer together.

Front

Define viscosity in the context of liquids.

Back

Viscosity is a liquid’s resistance to flowing.

Front

What is the primary characteristic that distinguishes solids from liquids?

Back

Solids have a definite shape and volume, while liquids have a definite volume but no definite shape.

Front

How do temperature changes affect the state of matter?

Back

Increasing temperature can cause solids to melt into liquids and liquids to evaporate into gases.

Front

What happens to the molecular arrangement when a liquid freezes?

Back

When a liquid freezes, its molecules slow down and arrange themselves into a fixed, regular pattern, forming a solid.

Front

What is the difference between evaporation and boiling?

Back

Evaporation occurs at the surface of a liquid at any temperature, while boiling occurs throughout the liquid at a specific temperature called the boiling point.

Front

What is the significance of the boiling point in relation to states of matter?

Back

The boiling point is the temperature at which a liquid turns into a gas, indicating a change in state from liquid to gas.
