What precautions should be taken while using a laboratory thermometer?
Handle the thermometer carefully to avoid breakage. Avoid touching the bulb of the thermometer with bare hands to prevent inaccurate readings due to body heat. Always calibrate the thermometer before use and store it properly when not in use to maintain accuracy. Follow proper disposal procedures if the thermometer breaks or malfunctions.
What will happen if you hold a mercury thermometer from its bulb?
If you hold a mercury thermometer from its bulb, the heat from your hand can cause the mercury to expand and rise in the tube, giving an inaccurate reading. Additionally, mercury is toxic, so it is not safe to handle a broken thermometer. Always handle thermometers by the plastic casing to avoid these issues.
Why is the wetbulb thermometer read lower than The dry bulb thermometer?
The wet bulb thermometer is typically read lower than the dry bulb thermometer because the evaporation of water on the wet bulb cools the sensor by removing heat from it. This process is known as evaporative cooling and results in a lower temperature reading on the wet bulb thermometer compared to the dry bulb thermometer.
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.
Which one is always higher wet bulb temperature or dry bulb temperature?
The wet bulb temperature is always lower than the dry bulb temperature. The wet bulb temperature is the temperature taken by a thermometer covered in a wet cloth and exposed to moving air, and it reflects the evaporative cooling effect.
Is The wet bulb thermometer reading is always higher than the dry bulb?
No, the wet bulb is always lower. Evaporation from the wet bulb reduces its temperature.
Is the wet bulb thermometer reading always higher than the dry bulb?
No, the wet bulb is always lower. Evaporation from the wet bulb reduces its temperature.
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 does bulb of a clinical thermometer break when placed in very hot water?
The bulb of a clinical thermometer breaks when placed in very hot water because the sudden increase in temperature causes the air inside the bulb to expand rapidly. This rapid expansion of air creates pressure within the bulb, leading to its breakage.
Why is the wetbulb thermometer read lower than The dry bulb thermometer?
The wet bulb thermometer is typically read lower than the dry bulb thermometer because the evaporation of water on the wet bulb cools the sensor by removing heat from it. This process is known as evaporative cooling and results in a lower temperature reading on the wet bulb thermometer compared to the dry bulb thermometer.
What do you do if a thermometer breaks?
If a thermometer breaks, evacuate EVERYONE out of the area including pets and small children
Would the temperature change on a thermometer if you hold it by the thermometer bulb?
Yes as your fingers are warmer than the air surrounding the thermometer bulb.

Explain how you would use a wet bulb thermometer and a dry bulb thermometer to find the relative humidity?
the wet bulb is cooler
Why is distilled water used on a wet bulb thermometer?
it is used in a bulb thermometer because the molocules a still
