I believe it’s True, but please correct me if I’m wrong!
The evaporation rate of the n-Hexane is 
<u>Explanation</u>:
This is a situation regarding diffusing A through non-diffusing B.
A = n-Hexane B=Air
Where the molar flux is provided by,



the vapor pressure at hexane

For wind, assume negligible hexane is present, hence 
Now,







where T = 298 K
substituting all in the equation, we get


Now,Flux
area = Molar rate of evaporation
Evaporation rate = 
Evaporation rate =
D. Camshaft gear backlash is being checked
hope this helps :)
Explanation:
Which stroke in the four stroke cycle begins as the piston reaches BDC after combustion takes place?
Answer :Exhaust stroke is the waste gasses discharging process into the atmosphere after the combustion stroke. This step takes place after the piston reaches the BDC at the end of the combustion stroke. When the piston reaches BDC, the piston will definitely move back to TDC.
This is the Answer for your question :3
I hoped I helped you :3
I hope you are having a great day ❤️❤️❤️
