Dew point is the atmospheric temperature at which dew can form. The measure marks the point to which the air must be cooled to reach a saturation point, as water vapor in the air condenses to form dew. Water vapor is the gaseous state of water or water in a gas form. The higher the dew point, the more moisture there is in the air. Now that we’ve met the dew point spec we can determine if we’ve met the heating value spec. We can determine this from additional properties calculated for Cold Vapor.
