If you know the temperature, volume, and pressure of a gas, how would you rearrange the ideal gas equation to find the number of moles?
Multiply PV by both T and R.
Divide PV by both T and R.
Divide PV by n.
Divide PV by T only.

Why can't all of the gas particles in a container have very high or very low speeds?
Because there is not enough pressure inside of a closed cont
Because as particles collide, a gain in kinetic energy other
Because there is not enough pressure inside
Because as particles collide they both increase their energy
