Explanation:

An element is the smallest part of a substance that is capable of independent existence. An element cannot be broken down into any other substance. Krypton, Bismuth etc are all elements.

A compound is a combination of two or more elements which are chemically combined together e.g NH3, CO2 etc.

A mixture is any combination of substances that are not chemically combined together. E.g Pizza, milk etc

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
