Buildings are more dense than the surrounding air. this means that they have more per volume than the air and will stay on the ground instead of floating up into the atmosphere. mass heat pressure temperature

Option (a) is the correct answer.

Explanation:

Density is defined as the mass present in a substance in per unit volume.

Mathematically,        Density =

Since, density is directly proportional to mass. Hence, more is the mass present per volume of a substance more will be its density. As a result, denser will be the object.

Therefore, we can conclude that buildings are more dense than the surrounding air. This means that they have more mass per volume than the air and will stay on the ground instead of floating up into the atmosphere.

the millers tale is the answer.

1. they vary with a higher number because boiling is way hotter than melting
