Answer» Answer:26.79% efficient Explanation: ASSUMING you have this question for Carnot cycle/engine, the formula for calculating efficiency of a carnot engine is => Efficiency = {1- (T1/T2)}*100 Where T1 is temperature of cold BODY and T2 is temperature for hot body(both in KELVIN). Here cold temperature T1 is 0°C = 273.15K And hot temperature T2 is 100°C = 373.15K Thus efficiency = {1-(273.15/373.15)}*100 => 0.267988*100 => 26.7988% The efficiency for this engine is 26.79% No a carnot cycle/engine can never be 100% efficient as to be 100% efficient, the SINK temperature should be 0K to infinite which are not POSSIBLE to achieve. |
