No, the wet bulb is always lower. Evaporation from the wet bulb reduces its temperature.
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.
It is swung through the air to speed up evaporation of water from the wet bulb thermometer.
It is important to immerse the entire bulb of the thermometer so that it can accurately measure the temperature of the substance. The bulb contains the temperature sensor, and if it is not fully submerged, it may not reflect the true temperature of the substance, leading to an incorrect reading.
On a dry day, water will evaporate from the wet bulb thermometer, cooling it. On a humid day, since moisture is already in the air, less will evaporate, and cool it less.
To find relative humidity using a wet bulb and dry bulb thermometer, first measure the temperature with both thermometers. The dry bulb thermometer provides the air temperature, while the wet bulb thermometer, which is moistened and exposed to airflow, measures the cooling effect of evaporation. Using the readings from both thermometers, you can refer to a psychrometric chart or use a formula to calculate the relative humidity based on the difference in temperatures. The smaller the difference between the two readings, the higher the relative humidity.
No, the wet bulb is always lower. Evaporation from the wet bulb reduces its temperature.

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.
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.
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.
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.
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.
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.
The bulb of a thermometer is usually made of glass to allow for expansion and contraction of the liquid inside. When the thermometer is subject to sudden changes in temperature, the glass can crack or shatter due to thermal stress, causing the bulb to break.
If the current is stronger then the bulb will be brighter.
The capillary tube is the hollow opening inside the thermometer that the liquid rises or lowers in so that you can read the temperature. The bulb is the bottom portion that holds the liquid and the part you use for contact to get a temperature reading. Calvin B.
The bulb of the thermometer must be submerged in the water because that is where the temperature of the water is accurately measured. The bulb is the part of the thermometer that contains the temperature-sensitive material, such as mercury or alcohol, which expands or contracts depending on the temperature of the water. This expansion or contraction is then displayed on the thermometer scale, giving an accurate reading of the water temperature.
