As we said, the ideal gas law uses are, which is our gas constant, but realize that the gas constant are can have two different values, depending on the situation. Now the two terms you'll tend to see when it comes to the are constant is the first one we talked about earlier are being equal 2.8 to 06 will utilize this value when dealing with the ideal gas law, but our can also equal 8.314 This happens when we're dealing with speed, velocity or energy. So if a question is dealing with the speed of an object or a subatomic particle, or dealing with the energy of a reaction or solution through our converts to 8.314 now, the conversion factor between the are groups is that one leader times atmospheres equals one on one point 3 to 5. Jules. So we have our 0.8 to 06 year. We use the conversion factor. So remember we want to get rid of leaders times, atmospheres. So we put them on the bottom. So one leaders times atmosphere here on the bottom is one on 1.3 to 5 jewels here on top leaders. Times atmospheres cancel out, and that's how we end up with jewels at the end. When you plug this in, you get a long string of numbers as 8.314 to 95 jewels over most times K. But we just focus on the 8.314 portion. I know there's a seven there when you work it out completely, but to keep it simple, books will just listed as 8.314 So just keep in mind the gas constant can be two different numbers. And remember what the ideal gas law We use this value, and when dealing with speed, velocity or energy, we use this value of 8.314
