Understanding Particle Movement and Energy

What happens to the kinetic energy of a high energy particle when it transfers energy to a low energy particle?

• It increases.

• It decreases.

• It doubles.

What is temperature a measurement of?

• The average kinetic energy of all particles.

• The potential energy of all particles.

• The speed of the fastest particle.

What leads to a higher temperature in a substance?

• Slower particles.

• Higher average kinetic energy of particles.

• No movement of particles.

What leads to a lower temperature in a substance?

• Faster particles.

• Slower particles.

• More particles.

What type of energy is related to the movement of particles within a substance?

• Potential energy.

• Kinetic energy.

• Thermal energy.

How do particles in a solid move?

• They move freely and quickly.

• They vibrate in fixed positions.

• They slide past each other.

How do particles in a gas move?

• They are tightly packed and do not move.

• They vibrate in fixed positions.

• They move freely and quickly.

What happens to the temperature of a substance during a change of state?

• It increases.

• It decreases.

• It does not change.

Which of the following is true about kinetic energy and temperature?

• Higher kinetic energy means lower temperature.

• Lower kinetic energy means higher temperature.

• Higher kinetic energy means higher temperature.

What is the relationship between particle speed and kinetic energy?

• Slower particles have higher kinetic energy.

• Faster particles have higher kinetic energy.

• Particle speed does not affect kinetic energy.
