Formulas and Key Relations

First law, heat, work, and sign convention

ΔU = q + w

ΔU = U2 - U1 = w_ad

w = -p_ex (V_f - V_i)

w = - ∫_{V_i}^{V_f} p_ex dV

w_rev = -nRT ln(V_f/V_i) = -2.303 nRT log(V_f/V_i)

Enthalpy and heat capacity

H = U + pV

ΔH = ΔU + pΔV

Cp - Cv = R

q_p = ΔH

Key relations

For reversible change, w_rev = -∫ p_ex dV.
