What is the primary difference in particle behavior between solids and gases?

• Particles in solids are free to move around.

• Particles in gases are tightly packed.

• Particles in solids vibrate in place, while particles in gases move freely.

• Particles in gases are locked in place.

How does the volume of an inflated balloon compare to an uninflated one?

• The inflated balloon takes up less space.

• The uninflated balloon takes up more space.

• Both balloons take up the same amount of space.

• The inflated balloon takes up more space.

What happens to the shape of a liquid when placed in a sealed container?

• It retains its original shape.

• It takes the shape of the container.

• It expands to fill the container completely.

• It evaporates immediately.

In a sealed container, how does the volume of a gas change?

• It becomes zero.

• It increases to fill the container.

• It decreases.

• It remains constant.

What is the effect of adding heat to a solid?

• Particles become more tightly packed.

• Particles stop moving.

• Particles move faster and begin to collide more.

• Particles move slower and closer together.

How does increased particle motion affect liquids?

• It causes the liquid to freeze.

• It stops the particles from moving.

• It makes the particles move closer together.

• It allows particles to slide past each other more freely.

What happens to the intermolecular forces when a liquid is heated?

• They disappear completely.

• They weaken, allowing particles to move more freely.

• They become stronger.

• They remain unchanged.

What occurs when a gas loses heat energy?

• Particles speed up and move further apart.

• Particles slow down and move closer together.

• Particles stop moving entirely.

• Particles become more energetic.

What remains unchanged when a substance changes state due to heat?

• The substance itself.

• The state of matter.

• The temperature.

• The volume.

What is the relationship between heat and particle motion?

• More heat means faster particle motion.

• Less heat means faster particle motion.

• Heat has no effect on particle motion.

• More heat means slower particle motion.
