The fuel is burned with more air case of (b) 70 percent excess air. This is because 70 percent excess air = 170 percent theoretical air which is more than in the first case.

Excess air is commonly defined as the percentage of total air supplied that is higher than what is needed for perfect combustion. A good rule of thumb for natural gas is to have about 10 cubic feet of air for every one cubic foot of fuel gas for perfect combustion.

The theoretical air is the lowest amount of air required for complete combustion of a fuel. If all of the carbon in the fuel burns to CO2, all of the hydrogen burns to H2O, and all of the Sulphur (if any) burns to SO2, the combustion process is complete.

Sedaris describes what for most of us would be a very unusual class—that is, a class in a foreign country with students from all
Marysya12 [62]

The essay “Jesus Shaves” by David Sedaris is part of his book <em>Me Talk Pretty One Day</em> and it tells the story of a French class he was in while studying abroad in Paris. The class is trying to explain to a Moroccan student what Easter is, but their lack of language skills make for a comical attempt.  

Part of the reason why the essay resonates with so many people is because of his description of experiences that are common to all students.

First, the fact that the Moroccan student asks a basic, obvious question that is very pertinent to the topic, yet no one really knows how to explain it despite its simplicity.  

Also, the way Sedaris defends American traditions when questioned by his teacher exemplifies the experience any student has when challenged by a professor.

Most importantly, the difficulty and frustration any language learner experiences when they are trying to explain themselves, yet they lack the words to do so as precisely as they would like.
