Question

Calculate the number of degrees of freedom in 15 cc of oxygen at 1 atm and 300 K. Also
calculate the total kinetic energy of the molecules of oxygen.​

Answer 1

Answer:

hydrogen molecule is diatomic so it has 3 translational degree of freedom and 2 rotational.

So degree of freedom in H

2

molecule =3+2=5

for number of molecule in 1cc

22.4lit=22400cc H

2

gas at STP has =6.023×10

23

molecule

1cc H

2

gas at STP has =

22400

6.023

×10

23

molecule =2.688×10

19

so total degree of freedom =5×2.688×10

19

=13.440×10

19

=1.344×10
