What does it mean when the two thermometers read nearly the same on a psychrometer?

It means that the relative humidity is high, because very little evaporation is taking place from the wet bulb.

What two temperatures read nearly the same on a psychrometer you can conclude that?
the air has a high relative humidity
When using a psychrometer and the two temperatures read nearly the same you can conclude that?
the air has a high relative humidityThe air has a high relative humidity
If both wet-bulb and dry-bulb thermometers read the same?
I believe that would mean that the air is completely saturated with moisture-- 100% humidity.
Why don't thermometers read down to -300 degrees Celsius?
Well, first of all, absolute zero, the point at which there is no thermal energy is at -273 degrees Celsius, so nothing could ever get to -300 C. Also, the mercury in the thermometer would freeze long before absolute zero, and it is unlikely that a standard thermometer would ever be used below its minimum measurement. If temperature measurement was needed below the minimum measurement of a thermometer, specialized scientific thermometers are available.
How can a sling psychrometer can measure relative humidity and dew point?
A sling psychrometer an instrument that measures relative humidity (a hygrometer). The sling has two thermometers, a dry bulb and a wet bulb thermometer, mounted together on a chain. The wet bulb thermometer is wrapped in muslin that is moistened with distilled water. The user then swings the sling until the temperatures stabilize, then quickly notes the two temperatures. To interpret the readings and determine the humidity, a chart is then used for the specific altitude at which the reading was taken. Basically, the drier the air is, the more moisture evaporates from the moistened muslin-covered thermometer, and the greater the difference between the two thermometers. If the relative humidity is 100%, then the two temperatures will be the same. Slings have been around for years, and are becoming less and less used for many reasons. With the advent of digital hygrometers, it's just easier to pull out a device and read the screen. Additionally, besides being cumbersome and time consuming, slings contain mercury, a hazardous material, and must be handled with care. A sling will typically read 5-10% high due to user error. Some of the mistakes that can be made while using a sling are: 1. If the sock on the wet bulb thermometer is not clean, the humidity measured from a sling will err on the high side. 2. If the water used for the wet bulb thermometer is not distilled water, the humidity measured from a sling will err on the high side. 3. If the sling is not swung around long enough, the humidity measured from a sling will err on the high side. 4. If the thermometer measurements are not read quickly enough after swinging the sling, the humidity measured from a sling will err on the high side. 5. If the charts used to interpret the results are not for the same altitude where the readings were taken, the humidity will be incorrect. Additionally, the charts are only available in 100' increments, and it is often difficult to determine the exact altitude of the user.

What does SP on the snow report mean?
Sling Psychrometer- A psychrometer in which the wet and dry bulb thermometers are mounted upon a frame connected to a handle. The psychrometer may be whirled by hand in order to provided the necessary ventilation.Snow Pellets- Precipitation of white, opaque grains of ice. The grains are round or sometimes conical. Diameters range from about 0.08 to 0.2 inch (2 to 5 mm).Station Pressure- The pressure that is read from a barometer but is not adjusted to sea level.Surface Pressure- The pressure that is read from a barometer but is not adjusted to sea level.Satellite Photo- A photograph of the earth taken by weather satellites that shows areas of cloud.
What is the purpose of the psychrometer?
The purpose of the psychrometer is to estimate Relative Humidity of Air. It does it by getting the dry and wet bulb temperatures. Then Relative Humidity is read on a chart.
Why do scientists use thermometers?
To read temperature...
Do thermometers that are facing south read higher temperatures?
No
What are Advantages of digital thermometers?
You can read the temp a lot easier.
If both wet-bulb and dry-bulb thermometers read the same?
I believe that would mean that the air is completely saturated with moisture-- 100% humidity.
Do all thermometers read the same?
No some read the temperature as Celsius, some as Fahrenheit, some as Kalvin
What are two types of thermometer?
The two types of thermometers are the total immersion and partial immersion thermometers. However, they both read temperature the same way!
Why is Mercury used in thermometers instead of alcohol?
Mercury thermometers have advantages over alcohol thermometers. The liquid is visible making the results easy to read. It expands at a regular interval. It measures temperature quickly and accurately.
What temperature Fahrenheit and celsius thermometers would read as the same number?
negative 40 degrees
