Change in temp vs Change in volume equations

Postby Nickolas Manipud 1C » Tue Feb 13, 2018 1:45 am

For these equations, , why is there a C for one equation and an R for the other

I think C is for constant volume, which is 3/2R, and R is just gas constant? Cv, constant volume, cannot be used for the second equation b/c volume is changing (V1 -> V2).

To add to the comment above, the C can imply either constant volume or pressure, due to the temperature change, either can be held constant. Constant pressure denoted (Cp) would be 5/2 R and Constant Volume would be denoted as (Cv) 3/2R.
