Presentation transcript:

The Ideal Gas Law Ideal Gas  Follows all gas laws under all conditions of temperature and pressure.  Follows all conditions of the Kinetic Molecular Theory (KMT)  An ideal gas does not exist in real life Real Gas  Follows some gas laws under some conditions of temperature and pressure.  Does not conform to the Kinetic Molecular Theory. Real gases have a volume and attractive and repulsive forces. A real gas differs from an ideal gas the most at low temperature and high pressure. Low T gas is moving less High P gas is more attractive

The Ideal Gas Law PV = nRT P = pressure V = volume n = number of moles R = Ideal Gas Constant T = temperature

PV = nRT 1. Calculate the number of moles of gas contained in a 3.00L vessel at 298K with a pressure of 1.50 atm.

PV = nRT 2. What pressure will be in kPa when there are mol of gas in a 5.00L container at 17.0 o C?
