right now, I'm following the MIT thermodynamics video lecture. I've gone thru dU = dw + dq (d for "is path dependent") and H = U + pV But why is enthalpy a function of temperature and pressure? is it because pV = nRT and thus, V = nRT/p, so we only need p and T to get V? dH = ( \delta H/...

why is rotational momentum I=mr²? I was studying for the AP physics and got stuck with this definition... ...So why is I = mr²? I looked at almost everywhere but couldn't find the answer...Please help this poor guy T_T... p.s: I looked at the internet and people just 'sways' away from...
