What is the ideal gas equation?

pV = nRT


p = pressure (Pa)

V = volume (m3)

n = number of moles (mol)

R = molar gas constant (J K-1 mol-1)

T = temperature (K)

How do you calculate work done on or by a gas at constant temperature?

W = pΔV


W = work done (J)

p = pressure (Pa)

Δ\DeltaV = change in volume (m3)
