Which statement best describes the compressibility of a gas? A Increasing the temperature of a gas decreases the pressure. B Inc
k0ka [10]

The answer is C. Compressing the air reduces the volume and increases the pressure. Compressing the air causes the molecules to collide with one another, and with the walls of the container, at a higher frequency. This is becaue the number of molecules are still the same but now forced in a smaller volume of space. This why the pressure increases wiht reduced volume, while keeping the temperatures constant.

A mole of Big Macs stacked would reach from the earth to the moon and back how many times?
OLga [1]
A mol=6.02*10^23
so
distance from earth to moon is 230,100 miles
1 big mac is about 2 inches
1 mile=5280 feet=63360inches

230,100 times 63360=14,579,136,000 inches is distance
6.02 times 10^23 times 2=x times 14,579,136,000
divide both sides by 2
6.02 times 10^23=x times 7,289,568,000
divide both sides by 6.02
10^23=x times 1210891694.35159
divide both sides by  1210891694.35159

Advertising claims sometimes state that adding something mechanical to a car's engine will allow it to recover 100 percent of th
Elan Coil [88]

Answer:

second law of thermodynamics.

Explanation:

The second law of thermodynamics deals with interconversion of energy from one form to another. Although energy can be converted from one form to another, this conversion is never 100% efficient because energy is lost in certain ways such as through heat. In a combustion engine, it is not possible to recover the energy from the gasoline 100% since energy must be lost along the way via such means as heat losses. Hence I will be skeptical about such an advert.
