What precautions should you take while using a laboratory thermometer?
The thermometer should be kept upright not tilted. 2.) The bulb of the thermometer should be surrounded from all sides by the substance of which the temperature is to be measured. 3.) The bulb should no touch the surface of the container.
How does a psychrometer work?
A psychrometer has two thermometers first off, second it can work by the bulb of the wet-bulb thermometer that has a cloth covering the moistened with water. Air is than blown over both thermometers. Because the wet -bulb thermometer is cooled by evaporation, its reading drops below that of the dry- bulb thermometer and dont let stalkers stalk you .. plus LOOK UP SKRILLEX ON YOUTUBE!! AWESOME!!!
Is the wet bulb thermometer reading always higher than a dry bulb reading?
No, the wet bulb is always lower. Evaporation from the wet bulb reduces its temperature.

Why must the sling psychrometer be swung to obtain the wet bulb reading?
It is swung through the air to speed up evaporation of water from the wet bulb thermometer.

In a thermometer an indication the temperature is dropping is?
In a liquid thermometer the liquid will retreat towards the reservoir bulb at the end of the thermometer. In other types of thermometers - digital, dial, etc. - decreasing values of the reading are an indication that temperature is dropping.
