States of Matter

These flashcards cover key concepts related to the states of matter, including definitions and characteristics of solids, liquids, and gases, as well as their practical implications in real-world scenarios.

What are the three states of matter?

Solid, liquid, and gas.

How can you identify a solid?

A solid has a definite shape and does not spread to cover the bottom of a container.

What happens to a solid when it becomes warmer?

It may melt and change into a liquid.

What defines a liquid?

A liquid has a definite volume but does not have a definite shape.

What happens to a liquid when poured from one container to another?

Its shape changes to match the new container, but its volume remains the same.

What is gas?

Gas does not have a definite shape or definitive volume and fills the entire volume of a container.

How can gases be detected despite being colorless?

Gases can be detected by their effects on other objects, like creating bubbles when blowing through a straw into water.

Why do travelers need special clothing at the South Pole?

Because the temperature is extremely cold, and they need clothing that holds in warmth.

What is the significance of the coexisting states of matter in a substance?

Most substances can exist in solid, liquid, or gas states depending on temperature.

What is a characteristic of a gas?

Gas fills the entire volume of its container.

What happens during the process of freezing?

A liquid changes into a solid when it cools down.

What is boiling or evaporation?

The process where a liquid changes into a gas when heated.

What is condensation?

The process where a gas changes into a liquid when cooled.

How do particles behave in a solid?

Particles in a solid are closely packed and vibrate in fixed positions.

How do particles behave in a liquid?

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

How do particles behave in a gas?

Particles in a gas are far apart and move rapidly and randomly, filling their container.
