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.

How is the Six's thermometer read?
The Six's thermometer is read by noting the lowest bulb containing a liquid that has risen above the height of the lower of the two threads. The temperature is then read directly along the scale where the top of the liquid intersects.
How does a fluid expansion thermometer work?
A fluid expansion thermometer consists of a bulb filled with a liquid, typically mercury or alcohol, connected to a capillary tube. As the temperature increases, the liquid in the bulb expands and rises up the capillary tube. The temperature is read by measuring the height of the liquid in the tube, which corresponds to the temperature scale on the thermometer.
What is a thermeter?
A thermometer is a tool used to measure temperature. It consists of a long, narrow tube with a bulb at one end that contains a liquid (such as mercury or alcohol) that expands or contracts with temperature changes. The temperature is then read from a scale on the thermometer.
Why you need to prevent the Mercury of thermometer from falling back with the constriction?
Preventing the mercury from falling back with the constriction in a thermometer ensures that the temperature reading remains accurate. If the mercury were to fall back into the bulb, the recorded temperature would be lower than the actual temperature, leading to measurement errors. The constriction acts as a barrier to prevent the mercury from moving back so that an accurate reading can be obtained.
What is formula of faulty thermometer?
One common formula for a faulty thermometer could be to read a value that is consistently higher or lower than the actual temperature. This could be due to an inaccurate scale or calibration issue.
What cause the wet bulb thermometer to read lower than the dry bulb thermometer?
because the water causes the temperature to be lower
How is the Six's thermometer read?
The Six's thermometer is read by noting the lowest bulb containing a liquid that has risen above the height of the lower of the two threads. The temperature is then read directly along the scale where the top of the liquid intersects.
What does it mean when a dry bulb thermometer reads the same temperature as a wet bulb thermometer?
When a dry bulb thermometer and a wet bulb thermometer read the same temperature, it indicates that the air is saturated with moisture and the relative humidity is 100%. This means that the air cannot hold any more moisture, resulting in no difference in temperature readings between the dry bulb and wet bulb thermometers.
How hot does a 75 watt light bulb get?
When measured with an infrared thermometer it read 169.9 degrees F.
What causes the thermometer with the wet sock to read lower than the thermometer with the dry bulb?
The rate of evaporation of water from the wet side, this is how relative humidity is measured. As the water evaporates it effectivly 'uses' some of the heat energy which would otherwise be heating the thermometer. The higher the relative humidity (water saturation of the air) the less water can evaporate and the lower the difference between the wet and dry side.
Why is it important to immerse the entire bulb of the thermometer in the substance whose temperature is being measured?
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.
What will the mercury thermometer show when it is kept in ice?
The question must be asked carefully. If the thermometer is in water ice and there is no liquid water, and there is one atmosphere of pressure, the thermometer can read anything from the freezing point of water and lower, depending on the range of the thermometer. If the thermometer is in a stable mix of water and ice, it will read the freezing point of water.
How to read a candy thermometer accurately?
To read a candy thermometer accurately, first make sure it is clean and dry. Clip it to the side of the pot, making sure the bulb is submerged but not touching the bottom. Read the temperature at eye level and wait a few seconds for it to stabilize. Take note of the temperature where the liquid inside the thermometer stops rising.
Where is the capillary tube and bulb in a thermometer?
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.
How does a fluid expansion thermometer work?
A fluid expansion thermometer consists of a bulb filled with a liquid, typically mercury or alcohol, connected to a capillary tube. As the temperature increases, the liquid in the bulb expands and rises up the capillary tube. The temperature is read by measuring the height of the liquid in the tube, which corresponds to the temperature scale on the thermometer.
How does a bulb thermometer work?
A bulb thermometer contains a liquid that expands when heated and contracts when cooled. This causes the liquid to rise and fall within the tube, indicating the temperature. The temperature is then read off a scale on the tube to determine the measurement.
Does a forehead thermometer read higher or lower than a rectal thermometer on a 2 month old baby?
At all ages rectal temperature is higher than skin temperature.
