Thermodynamics

Summary

• PV=nRT=Nk_BT
• P = pressure V = volume T = temperature R = Ideal gas constant (8.31 mol/J) n = number of moles k_B = Boltzmann constant
• Absolute temperature (kelvins)
• Extrapolating P-T or V-T graphs when V or P are constant will pass through in zero K.

Properties of an Ideal Gas

• Particles move at random instantaneous velocity and in all direction.
• Collision between gas molecules is elastic.
• Volume of individual gas particles is negligible to the gas volume.
• Gas molecules don't experience no appreciable forces except during collisions.
