Soil color does not affect the behavior and use of soil; however, it can indicate the composition of the soil and give clues to the conditions that the soil is subjected to.ark brown or black color in soil indicates that the soil has a high organic matter content. Wet soil will appear darker than dry soil. However, the presence of water also affects soil color by affecting the oxidation rate. Soil that has a high water content will have less air in the soil, specifically less oxygen.

It is very important to avoid such potentially dangerous thermal conditions before they can damage the component. By measuring a base temperature (such as ambient or case temperature), component temperature can be modeled and this can then be used to avoid harmful thermal conditions. This paper looks at two base temperature measurements, Case Temperature and Ambient Temperature. IntroductionAmbient Temperature and Derating Curves Ambient temperature is a term which refers to the temperature in a room, or the temperature which surrounds an object under discussion.
