(Q1) 1. Properties of Solids, Liquids, and Gases

Front

In a liquid, the particles are...

Back

close to each other.

Front

Which state of matter has the most kinetic energy?

Back

Gas.

Front

Which statement BEST explains why solids hold their shape?

Back

The particles form a rigid structure.

Front

In a gas, the particles are...

Back

widely spaced.

Front

What is the definition of a solid?

Back

A state of matter with a definite shape and volume, where particles are closely packed together.

Front

What is the definition of a liquid?

Back

A state of matter that has a definite volume but takes the shape of its container, with particles that are close together but can move past one another.

Front

What is the definition of a gas?

Back

A state of matter that has no definite shape or volume, with particles that are far apart and move freely.

Front

How does temperature affect the state of matter?

Back

Increasing temperature generally increases kinetic energy, which can change solids to liquids (melting) and liquids to gases (evaporation).

Front

What happens to the particles in a solid when heated?

Back

They gain energy and vibrate more, which can lead to melting.

Front

What happens to the particles in a liquid when heated?

Back

They gain energy and move faster, which can lead to evaporation.
