Kinetic Molecular Theory

• All particles are in constant, random motion

• All collisions between particles are perfectly elastic

• The volume of the particles in a gas is neglible

• The average kinetic energy of the moleculed is its Kelvin

Volume, Temperature, and Pressure

Volume def. - the three-dimensional space occupied by a solid, liquid, or gasunits - L, mLconversion methods - 1000ml = 1LTemperature def. - a quantitative measure of how hot or cold something is units - F, C, K conversion methods - c + 273 = k Pressure def.- the force of all the gas particle/wall collisions divided by the area of the wall units - atm, kPa, mmHg, torr conversion methods- torr-atm, atm-kPa, kPa-Pa

Ideal Gas Law

i. a description of gas behavior that permits you to solve for the number of moles of a contained gas when given one value each for P, V, and T ii. P and V are related and n, R, and T are related iii. R is constant iv. PV = nRT

Avogadro's Principle/Molar Volume

i. If temperature and pressure are held constant, then the volume of a gas is directly porportional to the # of moles of gas present ii. iii. STP - standard temperature (273K) and standard pressure (101.3 kPa)

Boyle's Law

i. for a given mass (moles) at gas at constant temperature, the volume of a gas change inversely with the changes in pressure ii. pressure and volume are related iii. temperature is constant

Charle's Law

i. the volume of a fixed mass (moles) of a gas is directly porportional to its Kelvin temperatue when pressure is constant ii. volume and temperature are related iii. pressure is constant iv. V1T2 = V2T1 v.

Gay-Lussac's Law

i. the pressure of a gas is directly porportional to its Kelvin temperature if volume and mass (moles) are held constant) ii. volume and temperature are related iii. volume and moles are constant iv. P1/T1 = P2/T2 v.

Combined Law

i. The law combines the laws of Boyle, Charles, and Gay-Lussac ii. pressure, volume, and temperature are related iii. moles are constant iv. P1V1/T1 = P2V2/T2
