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.
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.
What is a glass bulb of a thermometer?
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.
Why is it advised not to hold the thermometer by its bulb while reading it?
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.

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.
Explain how you would use a wet-bulb thermometer and a dry-bulb thermometer to find the relative 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.
How you would use a wet bulb thermometer and a dry bulb thermometer to find a hr relative humidity?
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.

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.
How would youwould use a wet-bulb thermometer and a dry-bulb thermometer to find the relative humidity?
USE as the air passes over the wet bulb thermometer the water in the cloth evaporates. as the water evaporates the cloth cools. if the humidity is low the water will evaporate more quickly and the...

the wet bulb is cooler
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.
What are the functions of a dry 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.
What is a glass bulb of a thermometer?
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.
