I have partial solutions from my tutorial but they are not making too much sense...
From the above equations, it goes:
K= 1/2 Nm <v>^2 so if divide each side by V
K= 1/2 ρ V <v>^2
from here the solution goes:
PV=1/3 Nm <v>^2
K=3/2 PV I can see that 2K=3PV
but i...
Find total kinetic energy and root mean square velocity of the molecules of 10 liters of helium gas at an equilibrium pressure of 105 N m−2. Density of helium is 0.1786 gram/liter.
I am having trouble with the question, I know:
K=(Nm<v^2>)/2
PV=(Nm <v^2>)/3
but I am not sure how to...
