Particle Theory and Change in State

Front

What is the particle theory?

Back

The particle theory states that all matter is made up of tiny particles that are in constant motion.

Front

What happens to particles when energy is added?

Back

When energy is added to particles, their speed, space, and temperature increase.

Front

What is the order of states of matter by increasing energy?

Back

Solid, Liquid, Gas.

Front

What change in state requires an increase in energy?

Back

Solid to Liquid.

Front

How does temperature affect particle movement?

Back

An increase in temperature results in an increase in the movement of particles.

Front

What is the state of matter with the least energy?

Back

Solid.

Front

What is the state of matter with the most energy?

Back

Gas.

Front

What happens to the arrangement of particles when a solid melts?

Back

The particles become less tightly packed and move more freely.

Front

What is condensation?

Back

Condensation is the process where gas turns into liquid, releasing energy.

Front

What is evaporation?

Back

Evaporation is the process where liquid turns into gas, requiring energy.
