I'm not sure if you still need help with this question, but I'll show how I'd work it out:
Firstly, to find the RMS (root mean squared) velocity of the molecules, we'll start with your equation,
PV=(Nm <v^2>)/3 Now we don't know N, and while we could calculate it, its easier to rearrange...
Sorry this is largely chemistry based, but delves into electron theory.
I'm a little confused about how the colour of transition metal compounds arises.
I understand that say for [Cu(H2O)6]2+, you have an octahedral arrangement around the central atom, and the specific positioning of these...
Sorry, I've read through this and I'm still a little confused.
Potential energy aside, what is the gravitational potential at the centre of the Earth (assuming constant density, and perfect spherical shape), and defining gravitational potential as the work done per unit mass moving an object...
