The amount of time that scuba divers can spend underwater is lim-ited by several factors, including time required to deplete the air sup-ply in their tanks. To make their air last longer, novice divers may be instructed to breathe slowly and exhale as much as possible on each breath. Can you suggest a reason why this behavior would lengthen a diver’s air supply?

Physical and Chemical features

The physical property of a compound could be determined without modifying the originality of the compound. Examples of physical properties are density, hardness, color, boiling, and melting point. The chemical property expresses the ability of a compound to undergo a particular chemical change.
