A = area

e = efficiency

F = force

h = depth

KE_ave = average molecular kinetic energy

l = length

M = molar mass

n = number of moles

N = number of molecules

P = pressure

Q = heat transferred to a system

T = temperature

U = internal energy

V = volume

v = velocity or speed

v_rms = root-mean-square velocity

W = work done on a system

y = height

α = coefficient of linear expansion

μ = mass of molecule

ρ = density

$P = P 0 + ρ g h$

$F b u o y = ρ V g$

$A 1 v 1 = A 2 v 2$

$P + \rho g y + \frac{1}{2}\rho v^2$

$Δ l = α l 0 Δ T$

$P = \frac{F}{A}$

$P V = n R T = N k b T$
