Kinetic Molecular Theory

Front

What is the state of matter in which materials have NO definite shape and volume?

Back

Gas state.

Front

What is an assumption of the kinetic-molecular theory of gases?

Back

The temperature of a gas depends on the average kinetic energy of the gas particles.

Front

True or False: States of matter never change, even when temperature or pressure change.

Back

False.

Front

What does 'kinetic' refer to?

Back

Motion.

Front

What is all matter made up of?

Back

Atoms.

Front

What is the kinetic molecular theory?

Back

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

Front

How do gas particles behave according to the kinetic molecular theory?

Back

Gas particles move freely and rapidly in all directions.

Front

What happens to gas particles when temperature increases?

Back

They move faster and have more kinetic energy.

Front

What is the relationship between temperature and kinetic energy in gases?

Back

Higher temperature means higher average kinetic energy.

Front

What is the difference between solids, liquids, and gases in terms of particle arrangement?

Back

Solids have closely packed particles, liquids have loosely packed particles, and gases have widely spaced particles.
