### Celcius vs Kelvin for T1 and T2

Do we need to be aware of any technical changes to the formula if we decide to use Kelvins vs Celcius in the calculations for temperature in both T1 and T2? Or should we just stick with Kelvin to be safe?

I say stick to Kelvin because that is typically what we use. Plus in most equations, the gas constant is in the equation which is 8.314 J/(K * mol).

Always use kelvin. You won’t get the right answer if you use Celsius

Always always always use Kelvin. Most standard konstants that we use are set for Kelvin, as well -- and I wouldn't suggest that you use the R values (for example) that use Celsius.

I think it's safe to always use Kelvin unless told otherwise. Chemistry pretty much prefers Kelvin over other temperatures.

you should always convert to Kelvin
