Fluid Dynamics for AP physics B

length is in meters, etc.-Kelvin.The ideal gas constant (R) is 8.13 Joules per mole Kelvin.Just gotta make sure your units match up.......
Im just wondering what the common unit was for temperature in PV = nRT, is it Kelvin? or is it Celcius?

cuz i know mass is in kg, length is in meters, etc.

Kelvin. The ideal gas constant (R) is 8.13 Joules per mole Kelvin. Just gotta make sure your units match up.

Uhhh that isn't fluid dynamics, that's the ideal gas equation.

It all depends on R. R is a constant, and you will be given R in a constant table for the test.

I can't remember which R is conventional for physics; the only one I know off the top of my head is .082 which is atm*L/(mol*K).

Oh...forgot that all R's would be in terms of Kelvin. So use Kelvin, and if you need reminding, check the constant table. Use Kelvin whenever you're dealing with temperature in equations unless you're talking about change (in which case it doesn't matter).

Usually it is Kelvin.
