What to Focus On

  • Temperature remains constant: ΔT = 0
  • Internal energy remains constant for an ideal gas: ΔU = 0
  • Boyle's law: PV = constant

  • No heat exchange: ΔQ = 0
  • Internal energy changes during the process
  • Poisson's law: PV^gamma = constant

  • Work formula: W = muRT loge(V2/V1)
  • Equivalent form: W = muRT loge(P1/P2)
  • Expansion gives positive work

Common Mistakes to Avoid

An adiabatic process means the gas must always change very rapidly.

Isothermal process means no heat exchange.

In an isothermal process, the internal energy of an ideal gas changes because the gas is doing work.
