Carbon dioxide concentrations are increasing in the atmosphere. Explain how this can lead to either a positive feedback loop (whereby carbon dioxide concentrations continue to increase) or a negative feedback loop (whereby carbon concentrations begin to decrease). Be specific in describing the steps of the feedback loop, and be sure to indicate whether it is a positive or negative loop.

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.
