Read each question carefully and answer to the best of your ability. Refer to the diagram of particle motion in different states of matter to help you answer some questions.
Observe the diagram below showing particle arrangements in different states of matter.
1. In which state of matter do particles have the most freedom to move past each other?
Solid
Liquid
Gas
Plasma
2. What happens to the motion of particles in a substance when it is heated?
They slow down
They speed up
Their motion remains unchanged
They stop moving
1. In a solid, particles are arranged in a fixed and vibrate in place.
2. Liquids have a definite volume but take the of their container.
3. Gas particles move and are far apart from each other.
1. Particles in a gas have less kinetic energy than particles in a solid at the same temperature.
True
False
2. When a liquid freezes, its particles gain kinetic energy and move more freely.
True
False
1. Describe the main difference in particle motion between a liquid and a gas.
2. Explain how adding heat energy affects the motion of particles in a solid.
