States of Matter

What is evaporation?

• The process of a liquid turning into a gas when heat is added.

• The process of a gas turning into a liquid when cooled.

• The process of a solid turning into a liquid when heated.

• The process of a liquid becoming solid when heat is removed.

What is the difference between kinetic and potential energy?

• Kinetic energy is energy of motion, while potential energy is stored energy.

• Kinetic energy is stored energy, while potential energy is energy of motion.

• Kinetic energy is the energy of an object at rest, while potential energy is the energy of an object in motion.

• Kinetic energy is the energy of an object in a gravitational field, while potential energy is the energy of an object in a magnetic field.

What happens to particles in a gas?

• They move quickly and are not in contact with each other.

• They are tightly packed and vibrate in place.

• They move slowly and are in contact with each other.

• They form a rigid structure and do not move.

What is a solid?

• A state of matter where particles vibrate in place and do not change relative positions.

• A state of matter where particles are far apart and move freely.

• A state of matter that has a definite shape and volume but can flow.

• A state of matter that can be compressed easily and takes the shape of its container.

What happens when the speed of particles decreases?

• Their temperature decreases.

• Their temperature increases.

• They move faster.

• They become more dense.

What is the relationship between temperature and particle motion?

• As temperature increases, particle motion increases.

• Temperature has no effect on particle motion.

• As temperature decreases, particle motion increases.

• Particle motion is inversely proportional to temperature.

What is kinetic energy?

• The energy of rest.

• The energy of motion.

• The energy of position.

• The energy of heat.

What is a liquid?

• A state of matter where particles are fixed in place and cannot move.

• A state of matter where particles move relative to each other but remain in contact.

• A state of matter that has a definite shape and volume.

• A state of matter that can be compressed easily.

What happens when the speed of particles increases?

• Their temperature increases.

• Their mass decreases.

• They move slower.

• They become solid.

What happens to particles in a solid?

• They vibrate in place and maintain fixed positions.

• They move freely and randomly throughout the material.

• They are in a gaseous state and spread out.

• They flow like a liquid and change shape.
