Unit Conversions

Postby Alexis Kupka 1H » Sat Jan 23, 2016 2:40 pm

When I was looking for work on problem 8.3, the solutions guide converted L x atm to joules by multiplying by 101.325J/L atm. Then when solving 8.9, the solutions guide used gas constants to convert to joules. Could i have just used the 101.325 again and if so why did the book use gas constants to convert the second problem?

Multiplying by 101.325J/L atm is basically the same thing as using the gas constants and converting to Joules.

For 8.9, yes you could have just used 101.325J/Lxatm instead of the gas constant.
