Question

Air is dense at sea level. It is the practical application of which law boyles law, Charles law or Gay Lussac law? Also please explain why. ..

Answer 1

Density of air at sea level:

Altitude is height above sea level. The density of air decreases with height. There are two reasons:

# at higher altitudes, there is less air pushing down from above,

#and gravity is weaker farther from Earth's center. So at higher altitudes, air molecules can spread out more, and air density decreases.

Answer 2

Hey there!

Boyle's law says that the volume of the gas change proportionally at the constant temperature. If air pressure increases at the constant temperature then volume is decreased and density of air is increased. And when we talk about sea level, there is both the things density of air and air pressure is maximum. That's why  air is more dense at sea level.

Hope it helps you!
