The bulb of a thermometer is used as a hot spot or "fire place" because as the temperature rises the bulb is heated which as heats the Mercury inside to estimate the outside temperature. So as you see the bulb attract to sunlight to heat itself like a hot spot.

Why you should not hold the thermometer by its bulb?

Holding the thermometer by its bulb can transfer heat from your hand to the bulb, affecting the temperature reading. This can lead to inaccurate results. It's best to hold the thermometer at the opposite end to prevent any interference with the measurement.

Why is it advised not to hold the thermometer by its bulb while reading it?

Holding the thermometer by its bulb can transfer heat from your hand to the bulb, affecting the temperature reading and providing inaccurate results. It's recommended to hold the thermometer by the stem to prevent any external heat sources from interfering with the measurement.


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.


What are the functions of a dry bulb thermometer?

A dry bulb thermometer is an ordinary one. It's given this name when it's used to measure air temperature. A wet bulb thermometer takes into account humidity.


How many thermometers are in a sling psychrometer?

A sling psychrometer typically contains two thermometers: a dry bulb thermometer and a wet bulb thermometer. The dry bulb thermometer measures the air temperature, while the wet bulb thermometer measures the wet bulb temperature after being moistened with water. These readings are used to calculate the relative humidity of the air.


What is used to measure heat in the air?

The best is a thermometer, another way to get the temperature outside is to pour water in a bowl, leave it out there for a couple of minutes and then take a thermometer and put it in the water.


Explain how you would use a wet-bulb thermometer and a dry-bulb thermometer to find the relative humidity?

To find the relative humidity using a wet-bulb thermometer and a dry-bulb thermometer, first measure the air temperature with the dry-bulb thermometer. Then, moisten the wick of the wet-bulb thermometer and expose it to airflow while taking the temperature reading. The difference between the dry-bulb and wet-bulb temperatures can be used with a psychrometric chart or formula to calculate the relative humidity of the air. This process works because the wet-bulb thermometer cools down through evaporation, and the greater the difference between the two temperatures, the lower the relative humidity.


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.


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.
