A "front" is the interface between two air masses of different temperature.
Their densities, temperatures, and locations are different.
boundary between two air masses of different temperatures and/or humidity levels
contact
50 to 300 degrees f.
Such a boundary is called a front.
The density. Refraction occurs at the boundary between two media of differing densities, such as air and water.
A "front" is the interface between two air masses of different temperature.
A boundary between two air masses of different temperatures and humidity is called a front. If a cold front meets a warm front head on, there is a possibility for a violent storm.
The direction of light propagation can be changed at the boundary of two media having different densities. This property is called refraction, and is illustrated in the following figure for the boundary between air and water.
Their densities, temperatures, and locations are different.
Anything between zero and millions of tons. Different materials have different densities, i.e., different amounts of mass per cubic centimeter.Anything between zero and millions of tons.

For the same substance, it will be less dense at higher temperatures and more dense at colder temperatures. There are a few exceptions, for instance water between 0 and 4 degrees C.
Of course, the densities are different.
