'''Ideal Gas Law''' For the <b>Gas Laws, Avogadro's Hypothesis and the Combined Gas Law</b>, the balloon (container for the gas) is changing some how. Therefore, there are <b>two conditions; one before and one after change</b>. For each condition, you will have parameters/variables (P,V,T,n). What happens if you are simply looking at a gas in a balloon (the balloon goes not change). Therefore, <b>there is only one condition</b>. So none of the equation we have been using are valid. The new equation called the <b>Ideal Gas Equation</b> should be used. It is '''PV=nRT''' where P is pressure of gas, V is the gas volume, T is temperature of gas, n is the number of moles of the gas, and R is called the <b>Ideal Gas Constant</b> which for our purposes will be <b>R = 0.0821 l-atm /(mole-K)</b>. <i>You approach these questions the same as any other gas equation.</i> The <b>one exception is the units</b>. <i>It is very important to understand that since you have the gas constant R in your equation, all other variable/parameters must have the units of the gas constant</i> (i.e. the pressure must be in atm so if it is not you must use your conversion factors to get it into atm). <br> <br> <br> ----<br> <b>2017-2018 Learners DO NOT DO BELOW</b><br> For an example of the calculation of ideal gas problems, see the website below. *[http://www.chemtutor.com/gases.htm Website to find info on Ideal Gas Law] *[http://www.ucdsb.on.ca/tiss/stretton/chem1/gases8.html Website with an example] *IdealGasLawMiniLab
