Physical & Inorganic Chemistry - Gases

This set of flashcards covers key concepts and terms related to the properties and behavior of gases as discussed in the lecture.

States of Matter

The three physical states of matter are solid, liquid, and gas.

Gas Characteristics

Gases expand to fill their containers, are highly compressible, and have extremely low densities.

Atmospheric Pressure

The weight of air per unit area, commonly measured in pascals (Pa) or atmospheres (atm).

Manometer

A device used to measure the pressure of a gas relative to atmospheric pressure.

Boyle's Law

States that the volume of a fixed quantity of gas at constant temperature is inversely proportional to its pressure.

Charles's Law

States that the volume of a fixed amount of gas maintained at constant pressure is directly proportional to its absolute temperature.

Avogadro's Hypothesis

Equal volumes of gases at the same temperature and pressure contain equal numbers of molecules.

Ideal Gas Law

Describes the relationship between pressure, volume, temperature, and number of moles of an ideal gas, expressed as PV = nRT.

Pascal (Pa)

The SI unit of pressure, equal to one newton per square meter (1 N/m²).

Partial Pressure

The pressure contributed by a single gas in a mixture of gases.
