Gases and Their Properties

Flashcards covering concepts related to gases and their properties as discussed in the lecture.

Kinetic Molecular Theory

The idea that particles are always in motion.

Pressure

Defined as the force per unit area on a surface, created when gases collide with the walls of its container.

Gas Behavior

Influenced by factors such as temperature, volume, and amount of gas.

Diffusion

The movement or mixing of material through another.

Elastic Collisions

Collisions between gas particles where no kinetic energy is lost.

Ideal Gas

A gas that obeys the gas laws under all conditions of temperature and pressure.

STP (Standard Temperature and Pressure)

Conditions defined as 0°C (273 K) and 1 atm (760 mm Hg) pressure.

Direct Relationship

A relationship where one factor increases as the other factor increases, or both decrease.

Indirect Relationship

A relationship where one factor increases while the other factor decreases.

Absolute Zero

The theoretical temperature at which molecular motion stops, represented as 0 Kelvin or -273°C.

Gas Law - Boyle's Law

States that pressure and volume of a gas are inversely related when temperature is constant.

Gas Law - Charles's Law

States that volume and temperature of a gas are directly related when pressure is constant.

Gas Law - Gay-Lussac's Law

States that pressure and temperature of a gas are directly related when volume is constant.

Gas Volume

The space that gas occupies, which can change with temperature and pressure.

Kinetic Energy (KE)

The energy of motion of gas particles, related to temperature.
