Kinetic Molecular Theory Flashcard

Front

What causes pressure in a gas according to the third postulate?

Back

The collisions of gas particles with the container walls.

Front

What does the second postulate of the kinetic molecular theory state about gas particles?

Back

They are mostly empty space.

Front

Rank the following samples from greatest kinetic energy of the molecules to least kinetic energy of the molecules: B, A, D, C.

Back

B > A > D > C.

Front

What happens to the average speed and total kinetic energy of gas molecules when the temperature increases?

Back

Average speed increases, total kinetic energy increases.

Front

What happens to the kinetic energy of gas particles when the temperature increases?

Back

It increases.

Front

Define Kinetic Molecular Theory.

Back

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

Front

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

Back

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

Front

Explain the concept of 'elastic collisions' in the context of gas particles.

Back

Gas particles collide with each other and with the walls of their container without losing energy.

Front

What is the significance of the volume of gas particles in the kinetic molecular theory?

Back

Gas particles are considered to have negligible volume compared to the volume of the container.

Front

How does the motion of gas particles relate to pressure?

Back

Increased motion leads to more frequent collisions with container walls, resulting in higher pressure.
