The Kinetic Theory of Matter: Definition & The Four States of Matter

1. The Kinetic Theory of Matter: Definition & The Four States of Matter

The kinetic theory of matter states that all matter is comprised of minuscule particles in random motion, with space between each particle. Learn about the definition of the kinetic theory of matter, phase changes, and the four states of matter.

The Kinetic Molecular Theory: Properties of Gases

2. The Kinetic Molecular Theory: Properties of Gases

Ideal gas molecules do not repel or attract each other, and professionals, like engineers, who work with gases need to recognize which gases are ideal. Learn how the kinetic molecular theory helps scientists and others understand the properties of ideal gases.

The Ideal Gas Law and the Gas Constant

3. The Ideal Gas Law and the Gas Constant

The ideal gas law can be used to predict real gas behavior. Learn about this law, including its equation, and understand how to use the equation to solve a gas problem. Explore the concepts used by the ideal gas law such as the gas constant.

Using the Ideal Gas Law: Calculate Pressure, Volume, Temperature, or Quantity of a Gas

4. Using the Ideal Gas Law: Calculate Pressure, Volume, Temperature, or Quantity of a Gas

The equation for the ideal gas law is PV = nRT. Learn how to use this equation to solve for the pressure in the atmosphere, volume in liters, number of particles in moles, the temperature in Kelvin, and the ideal gas constant.

Ideal Gas Law Problems & Solutions

5. Ideal Gas Law Problems & Solutions

The ideal gas law has four variables in it: moles, temperature, pressure, and volume. In this lesson, we will practice using the ideal gas law to calculate pressure, temperature and volume of gases.

Dalton's Law of Partial Pressures: Calculating Partial & Total Pressures

6. Dalton's Law of Partial Pressures: Calculating Partial & Total Pressures

Dalton's Law of Partial Pressures is used to calculate the partial and the total pressures of gases. Explore how gases behave after being mixed together and discover how to apply Dalton's Law to scientific problems concerning water vapor.

Real Gases: Deviation From the Ideal Gas Laws

7. Real Gases: Deviation From the Ideal Gas Laws

The behavior of real gases requires the use of a modified equation. Understand the ideal gas law, examine gas behavior assumptions, the Van Der Waals equation, and the deviations from the ideal gas laws.
