What happens to the mercury level when the cold thermometer is kept in a hot tub of water?
The mercury level in a thermometer placed in a hot tub of water will rise as the temperature of the water increases. This is because the volume of liquid mercury expands with higher temperatures, causing it to climb up the measuring scale in the thermometer.
How do you tell how hot or cold something is?
use a thermometer.We can feel how hot or cold something is. However, sometimes things are just too hot or cold for us to feel safely. At other times we need to know exactly how hot or cold something is. When we need to measure temperature correctly we need to use an instrument called a thermometer. This measures temperature in degrees Celsius [sometimes called centigrade] or degrees Fahrenheit. There are different types of thermometers for different situations. A medical thermometer, for example, needs to be very accurate. It measures in fractions of degrees. When we are ill, even tiny changes in temperature are important. Some thermometers use a liquid that moves up a very fine glass tube. Most room thermometers, and outdoor thermometers are like this. The liquid is either mercury [ which is poisonous] or coloured alcohol. As liquids get warmer they expand [get bigger], and move up the tube. Water expands too, but not as much as alcohol and mercury. Thermometers that might be used by small children are not made of glass. They use a digital display which lights up the temperature. Inside the displays are chemicals that change colour according to the temperature.
Why is the thermometer kept in the armpit?
The armpit is a common site for measuring body temperature because it is quick and non-invasive. It is a convenient and easily accessible area where the thermometer can accurately measure the body's internal temperature.
Why has my Galileo thermometer stopped working?
There are several reasons why a Galileo thermometer may stop working, including changes in temperature, air bubbles trapped in the liquid, or damage to the glass tubes. It is important to ensure that the thermometer is kept in a stable environment and handled carefully to prevent any issues with its functionality.
Why thermometer kept under toungue?
A thermometer is kept under the tongue to measure the body's core temperature accurately. The blood vessels under the tongue provide a good reflection of internal body temperature, making it a reliable location for temperature measurement. The mouth is also a convenient and non-invasive site for taking temperature readings.
What is a classroom thermometer?
A "classroom thermometer" is a thermometer assigned to be kept in a specific classroom.
Why doctor kept the thermometer under the arm?
When putting thermometer in the mouth of a crying child is difficult.
How do you get connected to the mercury?
When thermometer is kept inside the mouth
Why the thermometer kept under the tongue?
To measure temperature of the body.
When a thermometer is kept in the ice the reading shows?
Increases first and then decrease
Where a thermometer should be kept in determining melting point of ice?
A thermometer should be immersed in the ice water mixture in order to accurately determine the melting point of ice. This ensures that the thermometer is in direct contact with the substance being measured and will provide a precise reading of when the ice starts to melt.
Where should a thermometer be kept?
Out of the hands of children, in a place protected from mechanical shock and away from extremes of temperature that could exceed the range of the thermometer.
Which is other place than mouth where thermometer is kept to measure body temperature?
Armpit
What happens when a cold thermometer is kept in a hot tub of water?
the termometre gets warmer
Why thermometer kept in liquid?
so the germs are not spred to other people . TO KEEP CLINIC HYGINIC
What will the mercury thermometer show when it is kept in ice?
The question must be asked carefully. If the thermometer is in water ice and there is no liquid water, and there is one atmosphere of pressure, the thermometer can read anything from the freezing point of water and lower, depending on the range of the thermometer. If the thermometer is in a stable mix of water and ice, it will read the freezing point of water.
Why thermometer kept under tongue?
A thermometer is kept under the tongue because this location provides an accurate reflection of the body's temperature. The mouth is a good location for temperature measurement because blood flows close to the surface of the mouth, which allows for a quick and reliable reading.
