In simple terms, density describes how compact or concentrated an object is. ... Density also determines whether an object will float or sink in another substance. Polarity refers to molecules that are positively charged at one end and negatively charged at the other. It also determines how atoms bond with each other.

How does air density affect temperature?

Asked By: Vinko Vrsalovic Date created: May 18, 2022

Air Density and Temperature This is because warmer molecules of air move faster, creating an expansion effect that decreases air density.
