Ideal vs Real Gasses, Partial Pressure, and Effusion/Diffusion

Flashcards covering concepts related to ideal and real gases, including laws and properties.

Ideal Gas

A hypothetical gas that perfectly follows the gas laws under all conditions.

Real Gas

A gas that does not behave according to the ideal gas law due to intermolecular forces and molecular volume.

Ideal Gas Law

The equation PV = nRT, describing the behavior of an ideal gas.

Real Gas Law

The equation [P + a(n/v)²] (V - n*b) = nRT, accounting for the volume of gas particles and intermolecular forces.

Brownian Motion

The random movement of particles suspended in a fluid resulting from their collision with fast-moving atoms or molecules.

Elastic Collisions

Collisions between gas particles that do not lose kinetic energy.

Intermolecular Forces (IMF)

Forces of attraction or repulsion between neighboring particles.

Why don't we use the Real Gas Law often?

Because the Ideal Gas Law is a good approximation for real-world scenarios at low pressure and high temperatures.
