CI Inv 4 - Kinetic Energy

Front

What happens to particles in a closed system as they cool?

Back

They slow down and move closer together with fewer collisions.

Front

What is the term for the process when particles move closer together?

Back

Contraction.

Front

True or False: The number of particles changes when a system is contracted or expanded.

Back

False.

Front

How does kinetic energy change when a system is undergoing contraction?

Back

It decreases.

Front

What results in a smaller volume in a system?

Back

Increased pressure.

Front

What is kinetic energy?

Back

The energy that an object possesses due to its motion.

Front

What happens to kinetic energy when particles move faster?

Back

Kinetic energy increases.

Front

What is the relationship between temperature and kinetic energy?

Back

As temperature increases, kinetic energy increases.

Front

What is compression in terms of particle movement?

Back

A process where particles are pushed closer together, increasing pressure.

Front

What is the effect of decreased kinetic energy on particle movement?

Back

Particles move slower and are closer together.
