Definition A hypothetical law which obeys boyle’s law exactly at all temperatures and pressures, which has internal energy (Depends on the temperature) Also, there is no interaction between the individual molecule. Boyle’s law: A gas law stating that pressure and volume of a gas have an inverse relationship, when temperature is held constant =

What is the main focus? An ideal gas can be characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them may be deduced from kinetic theory and is called the ideal gas law.

The Equation PV = nRT Pressure: P= nRT / V Volume: V= nRT / P Mole: PV / RT Temperature: T= PV / nR

Real Life Examples Air Pressure in Airplanes- The Ideal Gas Law relates to this because you have to know how much oxygen is needed to put in the cabin, using the proper pressure, temperature, and volume that fits the plane.

Real Life Examples (Cont) The ideal gas law is related to Avogadro's law as well, Avogadro's law illustrates the proportional relationship between volume and the number of moles, if one increases.. So will the other. In this equation both temperature and pressure must be held constant which is related to the ideal gas law because it has an absolute pressure Air to the basketball (Gas molecules/Moles gettin forced inside Volume is raised and at full capacity Volume not at its full capacity

Practice Problems A sample of argon gas at STP occupies 56.2 liters. Determine the number of moles of argon and the mass in the sample.

Solution Rearrange PV=nRT to n= PV/RT n=[(1.00atm)(56.2L)} / [(0.08206 L atm mol-1)(273.0K)] n= 2.50866 mol Multiply the moles by the atomic weight of Ar to get the grams. 2.50866 x 39.948 g/mol = 100g
