Ideal Gasses flashcards

Ideal Gas

A theoretical gas composed of many randomly moving point particles that interact only when they collide elastically.

Ideal Gas Law

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

Pressure (P)

The force exerted by gas particles per unit area on the walls of a container, measured in atmospheres (atm), pascals (Pa), or millimeters of mercury (mmHg).

Volume (V)

The amount of space that a gas occupies, typically measured in liters (L) or cubic meters (m³).

Temperature (T)

A measure of the average kinetic energy of gas particles, measured in Kelvin (K).

Number of Particles (n)

The variable representing the amount of gas, usually measured in moles.

Boyle's Law

States that the pressure of a given amount of gas is inversely proportional to its volume when temperature is constant.

equation- P1V1=P2V2

Charles's Law

States that the volume of a gas is directly proportional to its absolute temperature when pressure is constant.

equation- V1/T1=V2/T2

Avogadro's Law

States that the volume of a gas is directly proportional to the number of moles of gas present at constant pressure and temperature.

equation- V1/n1=V2/n2

Gay-Lussac's Law

States that the pressure of a gas is directly proportional to its absolute temperature when volume is constant.

Equation- P1/T1 = P2/T2.

Combined Gas Law

Combines Boyle's, Charles's, and Gay-Lussac's laws into one equation: P1V1/T1 = P2V2/T2.

Density (ρ)

Mass per unit volume of a substance, which can be derived from the ideal gas law.

Molar Mass (M)

The mass of one mole of a substance, which can be calculated from the ideal gas law.

Pressure-Volume Relationship

if volume increases, pressure decreases, and vice versa, which aligns with Boyle's Law.

Volume-Temperature Relationship

if the temperature increases, the volume increases proportionally, following Charles's

Law.

Pressure-Temperature Relationship

an increase in temperature leads to an increase in pressure, consistent with Gay-

Lussac's Law.

Volume-Moles Relationship

More moles of gas mean a larger volume, as described by Avogadro's Law.
