The hydrometer and the smaller "dewcheck" for field work
each have articles in Wikipedia.org, "The World's Encyclopedia"
The dew point is the temperature where condensation begins.
The dew point is the temperature at which air becomes saturated with water vapor, leading to condensation. For example, "When the temperature drops below the dew point, dew forms on the grass in the early morning."
A pair of bulbs for measuring temperature and one is wet ted to give the temperature difference when it is spun in the air to cool the bulbs, or you can use a pressure vessel type with a mirror
The dew point is the temperature at which air becomes saturated with moisture and dew can form. For example, "The weather forecast predicted a high humidity with a dew point of 70 degrees Fahrenheit, indicating stifling conditions."
the answer is none
They use the standard laboratory urine test.
go to mayor office, to the thermostat, use hairdryer and thermometer, heat mirror to get the dew point, set the thermostat 5 C above the dew point
tools that the biologist use are microscopes, petri dish, laboratory, test tubes, beakers, and computers tools that the biologist use are microscopes, petri dish, laboratory, test tubes, beakers, and computers
To calculate the dew point when the air temperature is 26°C and the relative humidity is 77%, you can use the formula or an online calculator. The approximate dew point in this case is around 21.5°C. This indicates the temperature at which the air would become saturated with moisture, leading to condensation.
Dew point is essentially the temperature at which the air would become saturated. I believe to measure the dew point you would have to use a combination of a dry bulb and a wet bulb thermometer on a device called a sling psychrometer. Then take those temperature values that you get and plug them into a specific equation which I can't remember off the top of my head and/or look at a specific chart of dry bulb and wet bulb temperature values to determine the dew point.
this is a laboratory apparatus, usually use in holding substances. for example test tube...
You can use in the school laboratory any type of pH paper.
