Multiple Choice

What is the relationship between temperature and the movement of particles in matter?

• Temperature is unrelated to particle movement

• Temperature decreases as particle movement increases

• Temperature is a measure of how cold or hot matter is

• Temperature is only relevant in solids

Multiple Choice

• It decreases

• It remains the same

• It increases

• It evaporates

Multiple Choice
