Questions & Step-by-Step Solutions

For a reversible process, the efficiency of a Carnot engine is given by which formula?
  • Step 1: Understand that a Carnot engine is a theoretical engine that operates between two temperature reservoirs.
  • Step 2: Identify the two temperatures involved: T1 is the temperature of the hot reservoir (where the engine gets heat) and T2 is the temperature of the cold reservoir (where the engine releases heat).
  • Step 3: Know that the efficiency (η) of the Carnot engine measures how well it converts heat into work.
  • Step 4: Learn the formula for the efficiency of a Carnot engine, which is η = 1 - (T2/T1).
  • Step 5: Remember that T1 must be greater than T2 for the engine to work properly.
  • Carnot Engine Efficiency – The efficiency of a Carnot engine is determined by the temperatures of the hot and cold reservoirs, illustrating the maximum possible efficiency for a heat engine operating between two temperatures.
