Question

1. hot air rises due to its difference in ______. (1 point)

mass
weight
density
composition

Explanation:

When air is heated, its volume increases while the mass remains relatively constant. Using the formula for density \(
ho=\frac{m}{V} \), an increase in volume \( V \) (with mass \( m \) constant) leads to a decrease in density. Less - dense hot air rises above denser cold air. Mass is a measure of the amount of matter and doesn't directly cause the rising (as mass of the air itself doesn't change in a way that causes buoyancy in this context). Weight is \( W = mg \), and while related to mass, it's the density difference (via buoyancy principles) that causes the rising. Composition (the types of gases) isn't the key factor here as the main change is in volume and density due to heating.

Answer:

density
