States of Matter

Front

What is a liquid?

Back

A state of matter where particles move relative to each other but remain in contact, allowing them to flow and take the shape of their container.

Front

What is heat?

Back

The transfer of thermal energy from a warmer object to a cooler one.

Front

What characterizes the particle arrangement in a liquid?

Back

Particles are not closely spaced and can slide past each other.

Front

What happens to water when it freezes into ice?

Back

The water loses energy, which causes the particles to slow down and form a solid.

Front

What is a gas?

Back

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

Front

What is the difference between solids, liquids, and gases?

Back

Solids have a definite shape and volume, liquids have a definite volume but take the shape of their container, and gases have neither definite shape nor volume.

Front

What happens to the energy of particles in a solid when it melts?

Back

The solid gains energy, causing the particles to move more freely and transition into a liquid state.

Front

What is thermal energy?

Back

The total energy of all the particles in an object, related to temperature and heat.

Front

How does temperature relate to the states of matter?

Back

Temperature affects the energy of particles; higher temperatures generally lead to more kinetic energy and can change the state of matter.

Front

What is the process of condensation?

Back

The change of state from gas to liquid, occurring when gas particles lose energy.
