Condensation

• Condensation occurs when warm, moist air comes into contact with a cold surface. The cold surface causes water in the air to form liquid water drops present as condensation on the cold surface.
  
  

Moisture Content

• Water, also known as moisture, is present in most substances and foodstuffs. The moisture content of, for example, a coffee bean can be measured by completely drying out the bean and measuring the difference in weight with and without water.
  
  

Effects

• Condensation formed on the surface of a substance may subsequently be absorbed and become part of that substance's moisture content. For example, a dry leaf on a forest floor may attract condensation during the night when the air is colder. Over time, this condensation is absorbed into the fabric of the leaf.
