Thermocouples can measure a wide range of temperatures however accuracy is a common limitation. Thermometers give consistent results however they may become decalibrated easily. Mercury thermometers are extremely accurate but they cannot be used at temperatures below negative 38 degrees Celsius.

Yes, you can check the whether with an instrument. this instrument is called a thermometer. this is how it works... when it's freezing cold it should be below 0. when it's hot it should be at least above 10 degrees. These thermometers should be kept outside so the thermometer is absolutely right or it's close to the right answer. However, a hygrometer can be used to use relative humidity. Or it is how much water vapor is in the air.
Its clarity and percision , and relative intolerance of error
If a dry wick is present the temperature shown on both thermometers will be the same. This data, when entered into the psychrometric chart, will indicate that the air has 100% relative humidity.
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.
1, describe the methode of reducing the levels and thier relative advantages and disadvantages 2, writetypes of levelling instruments and methodes of leveling
Advantages include: good for identifying which species appeared first Disadvantages: does not provide an age in years Hope I helped!
disadvantage formal communicative network
You would use both to determine the relative humidity.
advantages:wide range of mechanical properties.fabricated with relative ease.economical to produce.disadvantages:relative high density.low electrical conductivity.inherent susceptibility to corrosion.
advantages: correctly shows the relative sizes of Earth's landmasses disadvantages: has distortion shows the landmasses near the edges stretched and curved
There are no disadvantages to coral reef because, animals live with and if there was problem they would just have to die cause its everywhere
the wet bulb is cooler
Advantage of a gravity dam is that every section will be stable and reliable. An Earth dam can overflow and collapse because of erosion.
A barometer measures the barometric pressure of the atmosphere. This has to do with the relative humidity. The more moisture suspended in the air, the more it weighs. A weather thermometer measures the temperature of the air.
a liquid changes its volume relative to its temperature
The rate of evaporation of water from the wet side, this is how relative humidity is measured. As the water evaporates it effectivly 'uses' some of the heat energy which would otherwise be heating the thermometer. The higher the relative humidity (water saturation of the air) the less water can evaporate and the lower the difference between the wet and dry side.
