It happens due to:
1)Insufficient evaporation taking place from the wet bulb due to salt and dust or other impurities on the muslin,or due to presence of no water on the muslin.
2)It maybe due to difference in sensitivities of both the thermometers whereby one of them is slow in recording sudden changes of temperatures.
3)Lastly,maybe due to faculty of broken thermometers.
What else can I help you with?
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 cause the wet bulb thermometer to read lower than the dry bulb thermometer?
because the water causes the temperature to be lower
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 is bulb temperature is lower than the dry?
Bulb temperature is typically lower than dry temperature because the bulb thermometer measures the temperature of the air without factoring in the effects of evaporation. The dry bulb temperature, on the other hand, accounts for the cooling effect of evaporation, giving a lower reading than the bulb temperature.
What is the effect of too high position of the thermometer bulb?
A thermometer bulb placed too high will measure a lower temperature than the actual temperature in the container, as it may not be fully submerged in the substance being measured. This can lead to inaccurate readings and potentially incorrect conclusions about the system being measured.
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.
A thermometer is placed in water in order to measure the water temperature. What would cause the liquid in the thermometer to drop?
If surrounding water temperature is lower than the water in the thermometer, heat will transfer from the water in the thermometer to the colder water causing the liquid in the thermometer to drop.
Why do you use rubbing alcohol in thermometer?
Rubbing alcohol is used in thermometers because it has a lower freezing point than water, allowing the thermometer to measure lower temperatures accurately. Additionally, alcohol has a wider temperature range than mercury, making it suitable for various types of thermometers.
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.
Which one is more sensitive in between two thermometer one having spherical bulb and another having cylindrical bulb?
cylindrical bulb is more sensitive than the spherical bulb.
