Adiabatic walls: no energy may be transferred as heat between the system and the surroundings → no heat added or removed and no change in entropy ○ ∆U=-W; ∆S=0 ● Diathermal walls: the temperature of the system and the surroundings are the same (thermal equilibrium: the surroundings are sufficiently large so that their heat capacity is infinite and they can transfer heat to or from the surroundings with no change in temperature) ○ Isothermal means that the system is in thermal equili...
