The walls of the long tube above the thermometer bulb are made thick to provide insulation and minimize heat transfer from the environment, ensuring that the temperature measurement at the bulb is accurate and not influenced by external temperature changes. Thicker walls also help protect the thermometer from physical damage.
What else can I help you with?
Why the stem of a clinical thermometer is thick?
The stem of a clinical thermometer is thick to allow for better heat conduction between the body and the thermometer bulb, ensuring an accurate temperature reading. A thicker stem also provides durability and strength to withstand repeated use.
Why is the bore on a clinical thermometer narrower directly above the bulb?
The bore of a clinical thermometer is narrower directly above the bulb to slow down the expansion of mercury and provide a more accurate reading. This design helps to prevent sudden changes in temperature from affecting the reading, making the thermometer more precise.
How is using a thin walled bulb affect the thermometer?
Using a thin-walled bulb in a thermometer can lead to quicker response times and more sensitivity to changes in temperature. This is because thin walls conduct heat faster than thicker walls, allowing the thermometer to react more quickly to changes in its environment. However, thin walls may also be more fragile and prone to damage.
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.
Thickness of glass of a bulb in a thermometer?
The glass in a bulb of a thermometer is typically very thin, around 0.5-1 millimeter thick. This thinness allows for efficient heat transfer from the measurement area to the thermometer sensor. The glass is also often chemically treated to make it more resistant to thermal shock and breakage.

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.
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.
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
What are two parts of psychrometer?
The two parts of a psychrometer is the dry-bulb thermometer and the wet-bulb thermometer.
What would happen if you placed the thermometer bulb above the junction of the condenser and the distilling column?
Placing the thermometer bulb above the junction of the condenser and the distilling column would measure the temperature of the vapors leaving the column. This temperature reading can help monitor the progress of distillation and identify when different components are being distilled.
