Why the thermometer is accurate?
To ensure that you can get accurate results,and thus making a correct statement.
Why might your thermometer not give an accurate?
Because of where it is positoned. If you wanted to know the room temperature, but the thermometer was in a place where it is cold, it may not give the correct value.
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 it necessary to insulate the bulb on the thermometer went taking the superheat of an evaporator?
So you can get a correct reading
How does a thermometer indicate the temperature of an object?
The heat of the object heats the metal tip and heats the liquid inside (usually mercury) until it expands, thereby filling the thermometer. Various tests are performed to determine at what length is what temperature.
What do you need to determine your temperature?
a thermometer
What are the numbers for hot or cold on a thermometer?
Both so the correct temperature on the thermometer can relate to the correct room temperature.
How do you determine the temperature of gel?
Stick a thermometer into it.
How do you spell thermomater?
A thermometer is an instrument for measuring temperature.
How do you spell themometer?
That is the correct spelling of thermometer (temperature measurement device).
Which instrument is used to determine how hot the day is?
Thermometer.
What instrument is used to determine the temperature of a substance?
thermometer
Is this how you spell thermoniter?
No. The correct spelling is thermometer.
How do you spell tharmomter?
The correct spelling is thermometer.
What is the purpose of hanging a thermometer outside?
The purpose of hanging a thermometer outside is to determine outdoor temperature near one's home. Due to the erratic weather reports, people have chosen to determine their own temperature by hanging a thermometer outside.
How do you correctly position the number lines on a thermometer?
NUMBERING is a correct position the number lines on a thermometer.
How do you spell formomiter?
The word here is likely "thermometer", which measures temperature.
