States of Matter

Front

What is sublimation?

Back

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

Front

What happens to the size of particles when a solid changes to a liquid?

Back

The size of the particles stays the same.

Front

What is absolute zero?

Back

Absolute zero is the theoretical temperature at which particles have minimum thermal motion and are not moving at all.

Front

In which state of matter are particles not moving at all?

Back

Particles are not moving at all in absolute zero.

Front

Which state of matter can be compressed?

Back

Gas can be compressed.

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 liquids 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 is melting?

Back

Melting is the process where a solid changes into a liquid when heated.
