Well just breath out while the thermometer is in you mouth which releases hot air which couses the thermomiter to rase up the tempeture I did it and it worcked

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.
What instrument measures how hot or cold something is?
A thermometer is an instrument that measures cold and heat, together with temperature variations.
Who is the inventor thermometer?
thermometer
What is a glass bulb of a thermometer?
thermometer
What is a probe thermometer?
this is a thermometer that can work twice as much as a normal thermometer or a thermometer that can check the temperature of two things at the same time
How do you measure temperature outside?
Purchase a good quality thermometer specific to the type of temperature you need to monitor; IE: Medical, cooking, pool or fish tank. There are different type, but digital thermometors are the most accurate.

Is 30 degrees Fahrenheit below zero?
The number 30 is above zero. Is this a trick question ? At the same temperature, a Celsius thermometer will read -1.
Thermometer is to air pressure as what is to air pressure?
You asked the question wrong. The analogy was : Thermometer is to Temperature as Barometer is to Air Pressure.A meteorologist uses his Barometer to measure pressure in millibars, very small changes in the atmosphere's pressure. He uses the Thermometer to measure the air Temperature.
How do you fake a fever with an ear thermometer?
I have used this trick with my mom many times, put the thermometer up against a hot light bulb then take it off when it reaches 75.3 it will keep on going up then when it reaches 102.0 start blowing on it.
What are the types of thermometer?
Celsius, Fahrenheit, and Kelvin.
Origin of the word thermometer?
Thermometer
What instrument measures hot or cold air?
a thermometer
How can you measure a body temperature?
What kind of thermometer you use to measure the body temperature
A device used to display the temperature?
a thermometer thermometer a thermometer
What instrument measures how hot or cold something is?
A thermometer is an instrument that measures cold and heat, together with temperature variations.
Will the temperature of a thermometer rise if you wrap a fur coat around it?
I'm sure your teacher thought he (or she) was being clever when he asked you that. It's sort of a trick question. He's expecting you to say yes, because people associate fur with increased warmth, so he's going to tell you that the correct answer is no. But the correct answer is that it depends on the temperature of the air trapped inside the fur before it was wrapped around the thermometer. This requires some explanation. If the thermometer and the fur are in the same room and have been for a while, then we can assume that the temperature indicated by the thermometer is also the temp of the fur. Wrapping the fur around the thermometer, in that case, will do nothing to raise the temp of the thermometer, because the fur is not a source of heat energy. It merely insulates the thermometer from the environment outside the fur. If, however, the thermometer were outside in the winter and the fur were in your cozy, warm house, wrapping the thermometer with that fur would raise the temp of the thermometer somewhat, because it would change to read the temp of the air trapped by the fur.
