KMT

Front

What happens to the direction and velocity of gas particles when they collide?

Back

They change direction and velocity.

Front

What keeps particles in a solid trapped in the same small volume?

Back

Strong attractions between particles.

Front

What occurs when a solid becomes a liquid?

Back

The increased movement of particles pushes them completely out of position, collapsing the organized structure.

Front

How do particles in a liquid behave?

Back

They move fast enough to break attractions and push other particles out of the way.

Front

How do particles in a gas behave?

Back

They move freely in a straight line until they collide with another particle.

Front

What is the kinetic molecular theory (KMT)?

Back

A theory that explains the behavior of gases in terms of particles in constant motion.

Front

What is the relationship between temperature and the kinetic energy of particles?

Back

As temperature increases, the kinetic energy of particles also increases.

Front

What is the effect of pressure on gas particles?

Back

Increasing pressure compresses gas particles, reducing their volume.

Front

What happens to the arrangement of particles in a solid when it melts?

Back

The organized structure collapses as particles gain enough energy to move freely.

Front

What is the difference between the movement of particles in solids, liquids, and gases?

Back

Particles in solids vibrate in place, in liquids they move around each other, and in gases they move freely.
