# Summary
* Gas pressure comes from atoms colliding with the wall and transferring momentum. $P=\frac{F_{\perp}}{A}$
* Gas pressure exists throughout the gas, not just against the walls.
* Temperature is average kinetic energy of atoms: $K_{avg}=\frac{3}{2}k_BT$
* Boltzmann constant: $k_B=1.380649*10^{-23} J*K^{-1}$
* Root-means-square speed links speed to kinetic energy: $\frac{1}{2}mv_{rms}^2$
* $K_{avg}=\frac{3}{2}k_BT=\frac{1}{2}mv_{rms}^2$
* $v_{rms}$ rises with temperature.
* Maxwell-Boltzmann Distribution shows spread of atomic speeds. Higher temperatures broaden the curve and increases the peak speed.
* Temperature must be Kelvin to work.
