Phases of Matter

Front

What are the three main phases of matter?

Back

Solid, liquid, and gas.

Front

How do solids differ from liquids in terms of shape and volume?

Back

Solids have a definite shape and volume, while liquids have a definite volume but take the shape of their container.

Front

What is the primary characteristic of gases regarding shape and volume?

Back

Gases have neither a definite shape nor a definite volume; they expand to fill their container.

Front

What happens to the kinetic energy of particles as matter changes from solid to liquid to gas?

Back

The kinetic energy of particles increases as matter changes from solid to liquid to gas.

Front

What is the definition of volume in the context of matter?

Back

Volume is the amount of space taken up by an object.

Front

How do the particle arrangements differ in solids, liquids, and gases?

Back

In solids, particles are closely packed in a fixed arrangement; in liquids, particles are close but can move past each other; in gases, particles are far apart and move freely.

Front

What is the effect of temperature on the phase of matter?

Back

Increasing temperature can cause solids to melt into liquids and liquids to evaporate into gases.

Front

What is the term for the process of a solid turning directly into a gas?

Back

Sublimation.

Front

What is the term for the process of a gas turning into a liquid?

Back

Condensation.

Front

How does pressure affect the phase of matter, particularly gases?

Back

Increasing pressure can compress gases, potentially turning them into liquids.
