In each cycle of a carnot engine, 104 j of heat is absorbed from the high-temperature reservoir and 51 j is exhausted to the lowtemperature reservoir. what is the efficiency of the engine?

the efficiency of the Carnot engine is e=0 .5060 (50.96%)

Explanation:

The carnot cycle effifiency e is calculated through

e = W/Q₂

where

W= work

Q₂= heat absorbed

Q₁= heat exhausted

from an energy balance

W= Q₂ - Q₁ ( the proportion of the heat absorbed that was not released was converted to work)

therefore

e=(Q₂-Q₁)/Q₂ = 1 - Q₁/Q₂ = 1 - 51 J/104 J = 0.5060 (50.96%)

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of c is as shown here in the image.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
