Semester 1 FINAL

How do the particles/molecules in a solid move compared to the particles in a liquid?

• The particles in a solid vibrate in place, while the particles in a liquid move past each other.

• The particles in a solid move freely, while the particles in a liquid stay close together.

• The particles in a solid move fast, while the particles in a liquid move slowly.

• The particles in a solid move past each other, while the particles in a liquid stay in place.

What happens to the particles/molecules in a gas when the temperature is increased?

• The particles slow down and move closer together.

• The particles speed up and spread farther apart.

• The particles stay the same and do not change.

• The particles move past each other more slowly.

Which of the following best describes how the particles/molecules move in a solid, liquid, and gas?

• Particles in a solid are spread out, while particles in a liquid are tightly packed.

• In a gas, particles move slowly; in a liquid, they move faster; in a solid, they vibrate.

• In a solid, particles vibrate in place; in a liquid, they move past each other; in a gas, they move quickly and spread apart.

• Particles in a solid and liquid both move slowly, but particles in a gas move very fast.

In which state of matter are the particles closest together?

• Gas

• Liquid

• Solid

• Plasma

When a solid melts into a liquid, what happens to the movement of the particles/molecules?

• The particles stop moving completely.

• The particles begin to move past each other more freely.

• The particles start to vibrate more slowly.

• The particles move closer together and form a solid again.

True or False: Gases expand to fill the space of their container?

• False

• True

How does the speed of the particles/molecules in a liquid change when it is heated?

• The particles slow down and move closer together.

• The particles move faster and spread farther apart.

• The speed of the particles does not change.

What is the difference between the particle/molecule movement in a gas and the particle/molecule movement in a liquid?

• Particles in a gas move very slowly, while particles in a liquid move quickly.

• Particles in a gas are spread far apart and move quickly, while particles in a liquid are closer together and move past each other.

• Particles in a gas are tightly packed and do not move, while particles in a liquid move freely.

• Particles in both gas and liquid move in the same way, only at different speeds.
