What does it mean when a dry bulb thermometer reads the same temperature as a wet bulb thermometer?
100% RH
What makes a liquid-in-glass thermometer sensitive to a small change of temperature?
a bulb with a thin glass wall
Why should you never hold the bulb end of a thermometer?
If you hold the bulb end, the thermometer will measure YOUR temperature instead of the temperature of the medium that you wish to measure.
How do you use a wet bulb thermometer and a dry bulb thermometer?
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 temperature reading on the wet bulb thermometer will drop. if the humidity is high only a little bit of water will evaporate from the cloth of the wet bulb thermometer and the change in temperature will be small.
Why is it important to immerse the entire bulb of the thermometer in the substance whose temperature is being measured?
if you dont put the whole bulb in, then the thermometer cant read the temperature accurately.
Why is it advised not to hold the thermometer by its bulb while reading it?
The temperature of your hand affects the reading of the thermometer.
What cause the wet bulb thermometer to read lower than the dry bulb thermometer?
because the water causes the temperature to be lower
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.
Why the level of mercury should change at all when the bulb of the thermometer is brought in contact with another object?
a liquid changes its volume relative to its temperature
What is meant by the statement a thermometer measures its own temperature?
When a thermometer reaches thermal equilibrium, the temperature of the thermometer and the substance it is measuring are the same. Therefore, the thermometer is essentially measuring its own temperature.
What is the function of constriction in clinical thermometer?
In case of ordinary thermometer if the thermometer is taken out the body whose temperature has been seen, the Mercury would fall down as the bulb gets cooled. But in case of clinical thermometer even after the thermometer has been taken out of the mouth of the patient the level of mercury would be held at the same level though the bulb falls to the room temperature. So doctor could see the temperature liesurely. To bring back the mercury to lowest level we have to give jerks to the thermometer by shaking it.
Why is the bulb of thermometer made of thin glass?
The bulb thermometer is made of thin glass so as to detect the slightest change in temperature. It is made of thin glass for visibility as well.
