How does a bulb thermometer work?
The bulb is the ball where most of the liquid is concentrated.
Why is the bulb of a thermometer the most important part of a liquid thermometer?
you can use two main liquid substances in a bulb of a thermometer - the one i can remember -alchol-another one i am almost certain of -mercury- i am sorry if the later one is incorrect -if you do know the awnser i would appecheate if you conferm it for me .Remember you do not need to be a member or do anything to write an awnser .
When the temperature increases the level of mercury in the thermometre rises why does this occur?
When the temperature rises the mercury ions have more energy. That means they move around faster. Because they are moving faster they are further apart from each other on average, therefore the metal expands in volume. Because of the shape of the inside of a thermometer the mercury can only rise upwards even though it expands in all directions.
Why the Mercury-in-glass thermometer first descends and then rise when put in flame?
When placed in a flame, the glass bulb expands rapidly. This increases the volume of the bulb and so the column descends. However, the glass then conducts the heat to the mercury so that it undergoes thermal expansion and the column rises.
What does it mean when a dry bulb thermometer reads the same temperature as a wet bulb thermometer?
100% RH
What will happen if you hold a mercury thermometer from its bulb?
is it dangeorous to hold a thermometer from its bulb
Why does mercury level goes down for a very short time when a mercury-in glass thermometer is placed in hot water?
The exterior of the bulb of the thermometer expands first, resulting in the mercury level to go down. After that the mercury in the bulb expands more than the glass bulb, resulting in the subsequent rise of the mercury level.
What is the use of a constriction in a thermometer?
It prevents the mercury from flowing back into the bulb.
What is the use of the constriction In the thermometer?
It prevents the Mercury from flowing back into the bulb.
What happens to the mercury in the thermometer when the air is cool?
In a mercury thermometer, the level of mercury falls as the temperature of the air around it cools.A mercury thermometer has a bulb of mercury at the bottom and a thin tube above it with markings in Celsius degrees or Fahrenheit degrees. When the temperature warms, the mercury expands and rises up the tube. When the temperature cools, the mercury contracts and shrinks back toward the bulb at the bottom.
Why is putting a thermometer bulb in a flame a bad idea?
It is a very good idea for the thermometer manufacturer, but it is a very bad idea for you because the thermometer bulb may blow out and release the dangerous mercury stored inside.
How does a bulb thermometer work?
The bulb is the ball where most of the liquid is concentrated.
What does a clinical thermometer consist of?
a clinical thermometer consists of mercury(Hg) concealed inside a glass tube with a bulb at the bottom. the bulb portion has the mercury and is thermo-sensitive. owing to the rise in temperature, when kept under the tongue of a patient, the mercury rises over the calibrated tube portion.
Why doesn't the mercury on a medical thermometer go down when it's removed from the body?
There is a kink put in the tube which carries the mercury up the thermometer, that is why it needs to be shaken to send it back to the bulb
Why does the mercury not fall or rise in a clinical thermometer when taken out of the mouth?
Mercury does not fall or rise in a clinical thermometer when taken out from the mouth because of the KINK present in it.
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 there a constriction in a clinical thermometer?
The constriction prevents the mercury from returning back to the bulb when the thermometer is removed from a particular body.
