States of Matter

Front

What is the definition of a solid?

Back

A solid is a state of matter that has a fixed shape and volume, with particles that are closely packed together.

Front

What determines the state of matter of a substance?

Back

The state of matter of a substance is primarily determined by temperature and pressure.

What is the characteristic of liquids that differentiates them from solids?

Back

Liquids have a definite volume but take the shape of their container, unlike solids which have a fixed shape.

Front

What happens to the particles in a solid when it is heated?

Back

When a solid is heated, its particles gain energy and may begin to vibrate more vigorously, potentially leading to a change in state to a liquid.

What is compression in terms of states of matter?

Back

Compression is the process of reducing the volume of a substance by applying pressure, which is more applicable to gases.

Front

Can liquids be compressed?

Back

Liquids are generally incompressible, meaning they do not change volume significantly under pressure.

Front

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

Back

The process of a liquid turning into a solid is called freezing.

Front

What is the difference between evaporation and boiling?

Back

Evaporation is the process where liquid turns into vapor at any temperature, while boiling occurs at a specific temperature called the boiling point.

What is a characteristic of gases?

Back

Gases have neither a fixed shape nor a fixed volume, and they expand to fill their container.
