Sup /sci/,

When calculating a volume of a gas using a varying pressure and temperature, does the temperature unit have to be degrees Celsius when the we're using pascals for pressure?

>> No.4510440

Excuse the typos.

>> No.4510441

Use kelvin.

That's what I thought. My prof didn't convert to Kelvin when we were calculating the volume of a gas using pascals for pressure.

>> No.4510447

I just knew that was going to be a good gif.

It depends on how it's used. If it's a ratio between temperatures, it has to be Kelvin. If it's a difference, it can be Kelvin or Celsius, since a degree is the same in each.

If you're using differences in temperature, ΔT, then you can use Celsius because it's scaled the same way as Kelvin. If you're dealing with a single T then it needs to be Kelvin.

That makes sense. It was a ratio in our case though. Guess she just fucked up.

Depends on the units of the gas constant.
