Boyle's Law

P2V2 = P1V1

Charles Law

V2 / T2 = V1 / T1

Avegadro's Law

P2 / T2 = P1 / T1

Combined Gas Law

P2 V2 / T2 = P1 V1 / T1

Ideal Gas Law

PV = nRT

Pascal's Principle

P = F / A

Change in Temperature

?T = Tf - Ti

Change in Velocity

?v = vf - vi

Change in Distance

?d = df - di

Change in Momentum

?p = pf - pi

Convert ºF to ºC

ºC = ºF - 32 / 1.8

Convert ºC to ºF

ºF = (1.8 x ºC) + 32

Convert ºC to ºK

ºK = ºC + 273
