So larger the Bulb so biger the movement of the indicator colum at changes of temperature.
Hope it helps

All bulb thermometers use a fairly large bulb and a narrow tube to accentuate the change in volume.
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
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.
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.
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.
Yes as your fingers are warmer than the air surrounding the thermometer bulb.

The two parts of a psychrometer is the dry-bulb thermometer and the wet-bulb thermometer.
A dry bulb thermometer is an ordinary one. It's given this name when it's used to measure air temperature. A wet bulb thermometer takes into account humidity.
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.
A glass bulb of a thermometer is the part at the bottom of the thermometer that contains mercury or colored alcohol that expands and contracts with temperature changes. This expansion and contraction of the liquid is what causes the thermometer to measure and display the temperature.
A sling psychrometer typically contains two thermometers: a dry bulb thermometer and a wet bulb thermometer. The dry bulb thermometer measures the air temperature, while the wet bulb thermometer measures the wet bulb temperature after being moistened with water. These readings are used to calculate the relative humidity of the air.
