What is the relationship between temperature and particle motion in substances?

Back

As temperature increases, the motion of particles increases. In hotter substances, particles move faster compared to cooler substances.

Front

What state of matter has particles that are far apart and move freely?

Back

Gas.

Front

What defines a solid in terms of shape and volume?

Back

A solid has a definite shape and a definite volume, with particles packed tightly together.

Front

What happens to the motion of particles when heat is removed from a substance?

Back

The particles slow down and get closer together.

Front

What is the defining characteristic of a liquid in terms of shape and volume?

Back

A liquid has a definite volume but not a definite shape; it takes the shape of its container.

Front

How do particles behave in a gas compared to a solid?

Back

In a gas, particles are far apart and move freely, while in a solid, particles are closely packed and vibrate in place.

Front

What occurs to the state of matter when heat is added to a solid?

Back

When heat is added to a solid, it may melt and change into a liquid.

Front

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

Back

Evaporation.

Front

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

Back

Condensation.

Front

How does pressure affect the state of matter of a gas?

Back

Increasing pressure can compress a gas, potentially turning it into a liquid if the temperature is low enough.
