basic States of Matter and Temperature Concepts

Front

What is deposition?

Back

Deposition is the process where gas changes directly into a solid without becoming a liquid first.

Front

What is sublimation?

Back

Sublimation is the process where a solid changes directly into a gas without becoming a liquid first.

Front

What is a supercritical fluid?

Back

A supercritical fluid is a state of matter that occurs between liquid and gas, where the substance has properties of both.

Front

What is temperature?

Back

Temperature is a measure of how hot or cold something is, specifically the rate at which particles vibrate.

Front

What is cold?

Back

Cold is the absence of heat.

Front

What are the three main states of matter?

Back

The three main states of matter are solid, liquid, and gas.

Front

How do particles behave in a solid?

Back

In a solid, particles are closely packed together and vibrate in place.

Front

How do particles behave in a liquid?

Back

In a liquid, particles are close together but can move past each other, allowing the liquid to flow.

Front

How do particles behave in a gas?

Back

In a gas, particles are far apart and move freely, filling the space available.

Front

What happens to particles when a substance is heated?

Back

When a substance is heated, its particles gain energy and move faster.
