Answer:
The efficiency of Carnot's heat engine is 26.8 %.
Explanation:
Temperature of hot reservoir, TH = 100 degree C = 373 K
temperature of cold reservoir, Tc = 0 degree C = 273 K
The efficiency of Carnot's heat engine is

Answer:
a. Wet, soft dough at 85 degrees Fahrenheit
Explanation:
Fermentation is an anaerobic process that transforms starches into simpler substances. The rising of dough is due to fermentation.
According to Harold McGee, 85°F (29°C) is the best temperature for fermenting bread dough. Temperatures below 85°F (29°C) take much longer to ferment, and temperatures higher than that result into unpleasant flavors in the dough.
Wet, soft dough is usually more preferable because it produces a softer bread.
