A large bulb increases sensitivity of a thermometer by allowing for more air to expand or contract, resulting in a greater change in temperature being detected. The larger surface area of the bulb also allows for more efficient heat transfer between the air and the thermometer, improving its accuracy and responsiveness to temperature changes.
What else can I help you with?
What does the sensitivity of thermometer depends on?
The sensitivity of a thermometer depends on the scale or division of measurement on its display. Thermometers with smaller divisions or scales have higher sensitivity as they can detect smaller changes in temperature. Additionally, the design and materials of the thermometer can also impact its sensitivity.
Does area of bulb of thermometer affect the sensitivity?
Yes, the area of the bulb of a thermometer can affect its sensitivity. A larger bulb will have more surface area to capture heat, making it more sensitive to temperature changes compared to a smaller bulb. This can result in quicker and more accurate readings.
Does a thermometer bulb have large heat capacity or small heat capacity?
A thermometer bulb should have.small heat capacity. In case if it has large capacity, the temperature of the substance will get lowered due to the large amount of heat absorbed by the thermometer bulb
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 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.
How do you increase sensitivity of mercury in glass thermometer?
Sensitivity of a thermometer is the length of increase of the liquid per degree rise in temperature. More sensitive means more noticeable expansion. So if you want to increase the sensitivity, you could have a thinner capillary tube, a larger thermometer bulb etc. :)sailesh

Why is the bulb of a thermometer large?
AnswerSo larger the Bulb so biger the movement of the indicator colum at changes of temperature.Hope it helpsFritzAll bulb thermometers use a fairly large bulb and a narrow tube to accentuate the change in volume.

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.
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 does bulb of a clinical thermometer break when placed in very hot water?
The bulb of a clinical thermometer breaks when placed in very hot water because the sudden increase in temperature causes the air inside the bulb to expand rapidly. This rapid expansion of air creates pressure within the bulb, leading to its breakage.
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.
