To reset a thermometer to zero, ensure the thermometer is at room temperature (around 68-72°F) and then adjust the calibration screw or button on the thermometer until it reads zero. If the thermometer does not have a calibration feature, it may need to be sent to the manufacturer for recalibration.

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.
Does a thermometer go up?
No, a thermometer doesn't physically go up. Rather, it measures and displays changes in temperature by using a scale or dial to indicate the temperature.
How do you increase the range of a thermometer?
To increase the range of a thermometer, you can use a thermometer with a wider temperature range or select a different type of thermometer that is capable of measuring higher or lower temperatures. Additionally, some digital thermometers allow you to switch between different units of measurement to expand their range.
How do you make thermometer more sensitive?
To make a thermometer more sensitive, you can use a thermometer with a smaller sensor or probe tip, as this will allow for faster temperature changes to be detected. Additionally, calibrating the thermometer regularly and keeping it clean can help improve its sensitivity. Finally, minimizing external factors that can affect the temperature reading, such as drafts or heat sources, can also improve a thermometer's sensitivity.
Why the alcohol level in a thermometer goes down when it's cold?
When the temperature drops, the alcohol in the thermometer contracts and takes up less space. This results in the alcohol level appearing to go down in the thermometer.
A sentence with the word thermometer?
Allison checked the thermometer and discovered that it was below zero degrees.
Freezing point on Celsius thermometer?
Of water, zero degrees
What is coldest thermometer reading -19 or -20?
1
When did Galileo make the thermometer?
Galileo made the thermometer in 1593.
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.
3 degrees celsius below zero is written as?
On a thermometer, temperatures above zero are written as positive and below zero as negative. How will a reading of 3 degrees celsius below zero be written?
How do you play command and conquer zero hour online?
You go to multiplayer and make a acount and there you go
Why are the numbers where they are on a thermometer?
The numbers are where they are because the person who made the thermometer scale decided which numbers go where.
What do you put the thermometer on on poptropica?
When you get to the lighthouse, you go up the stairs with the torch and your player will say something. Go to your inventory and equip the thermometer and it will place it for you.
What is the difference in degrees between negative 13 F and 58 F?
71 degrees. Add 58 plus 13. If you look at it on a thermometer 13 is well, 13 away from zero and 58 is 58 away from zero in the opposite direction. To go to negative 13 from positive 58 you have to go 58 degrees to get to zero and then 13 more to get to negative 13. So 58 plus 13 is 71.
Where is the thermometer on cyberchase quest 4?
You go to sensible flats and go to genral store, go to the first door, go in and answer the question. then the lady will give you the thermometer. happy 2 help :)
How would a thermometer has measure temperatures using the kelvin scale differ from one that measure temperatures using the celsius scale?
A thermometer measuring in Kelvin scale would have its zero point at absolute zero (0 K), where all molecular motion ceases. In contrast, a thermometer measuring in Celsius scale has its zero point at the freezing point of water (0°C). To convert between the two scales, you would need to add 273.15 to the Celsius temperature to get the Kelvin temperature.
