Question

As the building collapses, the volume of air inside the building decreases, while the mass of the air stays the same. This means that the _____ of the air inside the building will increase

Answer 1

I think the answer to your question is Density

Answer 2

Answer is: density.

Density is a measure of mass per unit of volume: d(air) = m(air)/V(air).

d - density of air.

m - mass of air.

V - volume of air.

For example, if we take:

m(air) = 1 kg.

V₁(air) = 100 dm³.

d₁(air) = 1 kg/100 dm³.

d₁(air) = 0.01 kg/dm³; density before the building collapse.

V₂(air) = 50 dm³.

d₂(air) = 1 kg/50 dm³.

d₂(air) = 0.02kg/dm³; density after the building collapse.
