Kinetic Molecular Theory Flashcard

Front

What is the Kinetic Molecular Theory?

Back

The Kinetic Molecular Theory explains the behavior of gases in terms of particles in motion. It states that gas particles are in constant, random motion and that their collisions with each other and the walls of their container determine the gas's properties.

What is the relationship between the volume of a gas and its pressure according to the kinetic molecular theory?

Back

The relationship is inversely proportional; as the volume decreases, the pressure increases, and vice versa.

Front

What happens to the speed of gas particles when the temperature increases?

Back

The speed of gas particles increases.

Front

What happens to the pressure of a gas when its temperature increases?

Back

The pressure of a gas increases when its temperature increases.

Front

What is the relationship between temperature and kinetic energy according to the kinetic molecular theory?

Back

Temperature is directly proportional to the average kinetic energy of the particles in a substance.

Front

What effect does increasing the number of gas particles have on the pressure of a gas?

Back

The pressure of the gas increases.

Front

Define pressure in the context of gases.

Back

Pressure is the force exerted by gas particles colliding with the walls of their container, measured as force per unit area.

Front

What is absolute zero?

Back

Absolute zero is the theoretical temperature at which all particle motion stops, equivalent to 0 Kelvin or -273.15°C.

Front

How does the kinetic molecular theory explain gas expansion?

Back

Gas expansion occurs because gas particles move freely and spread out to fill the available space, resulting in an increase in volume.

Front

What is the significance of the average kinetic energy of gas particles?

Back

The average kinetic energy of gas particles is directly related to the temperature of the gas; higher temperatures mean higher average kinetic energy.
