of a gas is the temperature at which the vapor in a space (at a given pressure) will start to condense (form dew) Dewpoint of a gas mixture is the temperature at which the highest boiling point constituent will start to condense
Temperature at which moisture will condense from humid vapors into a liquid state
The temperature at which condensation forms, it depends upon the saturation of the air Warm air can hold more water vapour than cold Thus when warm air is at 100% saturation, a reduction in temperature means that it is unable to support the volume of water vapour in suspension and liquid water condenses out
n the temperature to which air must cool to result in saturation or formation of dew
The temperature to which the air must be cooled for water vapor to condense and form fog or clouds
the temperature air would have to be cooled to in order for saturation to occur The dewpoint temperature assumes there is no change in air pressure or moisture content of the air
the temperature at which the water in the atmosphere will condense as drops on a surface
The temperature to which a given weight of air must be cooled at constant pressure and constant water-vapor content in order for saturation to occur When this temperature is below 0o C, (32o F) it is sometimes called the frost point
The dewpoint is the point at which air, when cooled at a specific pressure and moisture content, reaches the saturation point of water vapor In other words, when the temperature is lowered, this is the point at which condensation occurs or dew forms
The temperature to which air must be cooled at a constant pressure to become saturated Example: If the air temperature is 70 degrees and the dewpoint temperature is 70 degrees the air is saturated and dew will form i e, the relative humidity is 100%
