What to Focus On

  • The first law gives the balance of energy but not the direction of heat flow.
  • The first law cannot decide whether a process is possible or impossible.
  • For a cyclic heat engine, Q_1 - Q_2 = W.
  • Kelvin-Planck statement: no engine can convert all absorbed heat into work.
  • Clausius statement: heat cannot flow from cold to hot without work.
  • The two statements are equivalent.
  • Reversible processes are ideal and exactly reversible.
  • Reversibility requires no dissipative forces and very slow change.
  • All practical and natural processes are irreversible.

Common Mistakes to Avoid

The first law of thermodynamics is enough to decide whether heat can flow from cold to hot or whether an engine can convert all heat into work.

Kelvin-Planck statement and Clausius statement are two different laws with different importance.

A heat engine can convert all the heat taken from the source into work if the design is good enough.
