I wouldn't think that there would be any situation where we need to convert to Pascals since Lavelle didn't talk about that unit at all. I think its important to just read the question and figure out what units they want their final answer in.

I don't think we will have to convert to pascals since Dr. Lavelle hasn't mentioned it yet. We will most likely be given atm or bar units for pressure.
Its probably best to leave it in ATM right now or for possibly the entire class but really each one of them has its own R value in the ideal gas law which you can search up or calculate just using the conversion factor (Although that method kinda takes away the whole point of leaving it in another unit). Just make sure not to use the wrong unit with the wrong R value and convert at the end to the unit the question is asking for.
I'm pretty sure we use atm because its units line up with the R value we are given on the equation sheet so the units can cancel, but in the lecture he said that 1 atm is also pretty close to 1 bar if you're wondering.
Okay, thank you for letting us know! Does anyone know if for the test if we are expected to know how to convert from Barr to atm or atm to pascals? I'm not sure if it was mentioned in the section outline or if this was just for practice on the homework and such.
