Why are two different metals needed when making a bimetallic strip for a thermoteter?
because the strip has to go inside the thermometer so it needs to metals just to make it go inside the thermometer :) #loving my life :)
How do you increase the range of a thermometer?
If you're the one designing the thermometer, you could make it longer or make the bore wider. If you've got an existing thermometer, there's not much you can do.
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 is meant by absolute zero of temperature?
It is the coldest temperature. Nothing is colder than absolute zero. Scientists do know what happens in absolute zero because to get it to absolute zero, they have to put the object in something colder. But like mentioned above, nothing is colder than absolute zero. It is pretty much the end of the thermometer.
Who invented the first thermometer ever?
Various authors have credited the invention of the thermometer to Cornelius Drebbel, Robert Fludd, Galileo Galilei or Santorio Santorio. The thermometer was not a single invention, however, but a development. If you go to Wikipedia, you can learn more about it.
A sentence with the word thermometer?
Allison checked the thermometer and discovered that it was below zero degrees.

When did Galileo make the thermometer?
Galileo made the thermometer in 1593.
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?
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.

How do you play command and conquer zero hour online?
You go to multiplayer and make a acount and there you go
When you put a thermometer into a pot of melting ice when will the temperature rise past zero?
when all the ice has melted
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 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.
