Key Points

  • The pressure exerted by the spring on the walls of the box is constant at p= 105 Pa regardless of its volume.
  • The volume increases and the pressure decreases, since the gas is doing work while it receives heat.
  • The temperature of a body is a quantity that indicates its level of internal excitation.
  • In conclusion, if the Kelvin–Planck statement is correct, then the Clausius statement must also be correct.
  • The partial pressure of a substance in a real gas mixture is in general different from the pressure of the pure substance at the same T and V , because the intermolecular interactions are different.
  • If there is a liquid junction between electrolyte solutions of different composition, slow diffusion of ions through the junction is inevitable.
