WebIt contains methylene chloride (mixed with a dye) in the abdomen, which boils at a very low temperature—about 100ºF 100ºF. To operate, one gets the bird’s head wet. As the … WebKey Points. The second law of thermodynamics indicates that a Carnot engine operating between two given temperatures has the greatest possible efficiency of any heat engine operating between these two temperatures. Irreversible processes involve dissipative factors, which reduces the efficiency of the engine.

Web19 okt. 2024 · Absolute zero has been considered the lowest temperature possible since the 1800s when Lord Kelvin developed his temperature scale. Now physicists working … WebT c o l d = 20 o C + 273 = 293 K. Step 2. Determine the efficiency using the Carnot efficiency formula: η = [ 1 − T c o l d T h o t] × 100 % η = [ 1 − 293 K 813 K] × 100 % = 64 %. From the Carnot Efficiency formula, it can be inferred that a maximum of 64% of the fuel energy can go to generation. To make the Carnot efficiency as high as ... draw a stickman epic 2 animation
