Example 4.c.1

Postby Matthew ILG 1L » Mon Feb 10, 2020 3:21 pm

I am on problem 4.c.3 in the book, and the example 4.c.1 is very similar to it. However, in the example, it says that Cv=5/2R, and that Cp=7/2R because in the book Cp=Cv+R.
On our equation sheet, it says that Cp=5/2R. I am confused as to which ratio is correct for Cp and Cv when converting to R.

I'm pretty sure you use Cv = 3/2R and Cp=5/2R if it's an ideal gas (monatomic) and you use Cp=7/2R and Cv=5/2R if it's diatomic.

If you look in the textbook page 265 it shows how Cp in monatomic gases is 5/2R and Cv for monatomic gases is 3/2R
