States of Matter and Particle Behavior

These flashcards cover key concepts related to the states of matter, particle behavior, and related vocabulary.

What happens to volume when pressure increases?

Volume decreases when pressure increases.

What causes a liquid to turn into a gas?

A liquid turns into a gas because it gets heated.

What happens when steam cools down?

Gas turns into a liquid when it cools down.

What is the process called when a solid turns directly into a gas?

The process is called sublimation.

What is dry ice an example of?

Dry ice is an example of a solid turning directly into a gas.

What occurs when gas turns into a solid without becoming a liquid?

This process is known as deposition.

What is the coldest temperature possible called?

It is referred to as absolute zero.

What occurs when an atom loses electrons?

It gives the atom a positive charge.

What is the temperature at which a substance changes between solid and liquid called?

This temperature is known as the melting point.

What is the energy of motion in relation to particles?

It explains how fast particles move.

How do gas particles behave?

Gas particles move fast, randomly, and are far apart.

What is a characteristic of solid particles?

Solid particles are tightly packed and have a fixed shape.

What describes a liquid's shape and volume?

A liquid has a definite volume but takes the shape of its container.

What defines a gas?

A gas has no definite shape and the particles move freely.

What is plasma?

Plasma is a super hot gas with charged particles, like lightning.

What does temperature measure?

Temperature measures how hot or cold something is and reflects particle movement.

What defines pressure in a gas?

Pressure is the force of gas particles hitting the walls of their container.

What is density?

Density measures how tightly matter is packed (mass per volume).

What is the relationship between temperature and volume?

When one goes up, the other goes up too (like temperature and volume).
