What materials do you need for the experiment of water temperature?
a thermometer
What are the materials used for a Galileo thermometer?
A Galileo thermometer is a thermometer made of a sealed glass cylinder containing a clear liquid and a series of objects whose densities are such that they rise or fall as the temperature changes.
What are some examples of smart materials?
This can be a thermometer which changes couler when hot or cold
What is thermometric substance?
These are materials used in thermometer whoses property varies with temperature
What makes a thermometer?
what are the sulfide mineral used to a thermometer
Why does liquid inside a thermometer rise as the temperature s increase?
Most materials expand with the temperature increases. In this case, the liquid in the thermometer expands faster than the glass that holds it.
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 a thermometric substance?
Thermometric substance is the material used in the thermometer, whose property varies with temperature.
Why don't you make thermometers with water?
You can make a thermometer with water, and in fact Galileo invented a rudimentary water thermometer in 1593. However, using other materials such as alcohol or mercury allows you to measure a greater variation in temperature.
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
