A thermometer does not have a dew point.
A thermometer is a fixed volume system where the temperature measurement capability is based on the material. As temperature changes, the density of the material expands or contracts. This implies the material used is in a liquid state.
By simple definition, the dew point is the temperature as which a material in the gas state condenses to a liquid.
additional. Dew point is a measurement made to determine the Relative Humidity of the atmosphere. In practice, it is a tiny mirror, which can be heated or cooled automatically, thus determining the dew point.
A light beam looks at the mirror, and when there is slight misting, the light intensity and focus are degraded, and that is the dew point. A built in thermometer measures the actual temperature.
So it is a complex, but small instrument consisting of :- a mirror, a heating and cooling circuit, a thermometer, and an optical scanner.
Dew point is considered an accurate measure of humidity, and since we also know the atmosphere's temperature, the relative humidity may be determined.
What else can I help you with?
Under what conditions will dew not form?
If the temperature of the ground, grass, and other surfaces is warmer than the dew point of the air that comes in contact with the surfaces, dew will not form. Sometimes this happens when the air is really dry and the dew point is very low.
Water vapor in the air condenses into liquid droplets when the water reaches .?
dew point
What is the dew point and what happens when it falls below the dew point?
The Dew Point is the temperature at which the air is at 100% Relative Humidity. If the temperature fall below the Dew Point, then there is more moisture in the air than it can hold, and water condenses in the form of dew, mist, rain, etc.
A sentence for dew point?
The dew point controlled the temperature of the air.
What is a psycrometer?
This is an instrument used to measure the relative humidity in the air.[Another way of determining this is to measure the dew point of the air. The temperature at which dew will form on a clean mirror that can be chilled. ]
What has two thermometers (a wet bulb thermometer and a dry thermometer)?
A psychrometer has two thermometers: a wet bulb thermometer and a dry bulb thermometer. It is used to measure relative humidity and can also determine dew point.
What happens when air has reached its dew point?
condensation Another question that follows: As an air mass cools to its dew point; relative humidity increases
Describe what happens when water vapor rises and cools to the dew point?
As water vapor cools to the dew point it converts from a gas back to a liquid.
What happens when air that has reached its dew point cooled further?
Condensation
Under what conditions will dew not form?
If the temperature of the ground, grass, and other surfaces is warmer than the dew point of the air that comes in contact with the surfaces, dew will not form. Sometimes this happens when the air is really dry and the dew point is very low.
What happens when air is cooled below its dew point without condensation?
supercooled
What happens wen a air mass cools to its dew point?
it grows testicles
Explain the relationship between condensation and dew point?
Condensation occurs when air reaches its dew point, which is the temperature at which air becomes saturated with moisture and can no longer hold it in gaseous form. When air cools to its dew point, water vapor in the air condenses into liquid water, forming dew or fog.
Water vapor in the air condenses into liquid droplets when the water reaches .?
dew point
How is dew point different from condensation?
the realationship between condensation and dew point is that condensation occurs when it reaches the dew point.
What is the dew point and what happens when it falls below the dew point?
The Dew Point is the temperature at which the air is at 100% Relative Humidity. If the temperature fall below the Dew Point, then there is more moisture in the air than it can hold, and water condenses in the form of dew, mist, rain, etc.
What happens when air that has reached its dew point is cooled further?
Relative humidity increases
