Gas Laws and Properties

Flashcards for key concepts related to gas laws and properties, focusing on definitions and real-life applications.

States of Matter

Matter exists in three states: solid, liquid, and gas.

Intermolecular Forces in Gases

Gas molecules have large intermolecular space and weak intermolecular forces.

Variables of Gas Properties

The properties of gas depend on temperature, pressure, and volume.

Standard Temperature

Standard temperature is 273K.

Standard Pressure

Standard pressure is 1 atm.

Boyle’s Law

At constant temperature, the volume of gas is inversely proportional to its pressure.

Real Life Application of Boyle’s Law

Examples include syringes, respiration, and bicycle pumps.

Charles’s Law

At constant pressure, the volume of a given quantity of gas increases or decreases by 1/273 of its volume at 0°C for each 1°C change.

Real Life Application of Charles’s Law

Examples include hot air balloons, baking, spray cans, and breathing.

Avogadro’s Law

Equal volumes of all gases under identical conditions contain equal numbers of molecules.

Avogadro’s Number

1 mole = 6.023 x 10²³ molecules.

Gay Lussac’s Law

At constant volume, the pressure of a gas is directly proportional to its temperature.

Ideal Gas Equation

PV=nRT relates pressure, volume, temperature, and number of moles of gas.
