What is the substance in a digital thermometer that tells us the temperature?
I don't think any substance is used in digital thermometer but according to my views "HEAT SENSORS" are used to measure the temperature.
What tells us how close air is to saturation?
The name for this is relative humidity.It is most often measured by a "wet and dry thermometer". This is just two thermometers, one of which is kept wet by a cloth wick dipping into a small pot of water. The other is, well, dry. The dry one indicates the air temperature. The wet one shows the same temperature minus the cooling effect of the water evaporating around the wet bulb. The higher the relative humidity, the less the evaporation and the smaller the difference in temperature. These thermometers are sold witha set of tables that calculate the R.H. from the two temperatures.

What does aq s g and l mean in chemistry?
These are called "state symbols". In chemical equations, they tell us what form the compounds/elements etc. are present in: * (s) tells us that the substance is solid, such as 'CaCO3(s)' * (l) tells us that the substance is liquid or molten, such as 'H2O(l)' * (g) tells us that the substance is gaseous, such as 'CO2(g)' * (aq) tells us that the substance is in solution ie. aquaeous, such as 'HCl(aq)'
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 are the name of the instruments use in measurement?
Measuring Instruments. 1. ruler 2. Thermometer 3. Light meter 4. Isomerism 5. Metric Ruler:- It is used to measure length. Thermometer:- It is used to measure temperature. Light Meter:- It tells us about the brightness. Isomerism:- It is used to measure the motions of the ground. Metric:- It is the measuring Instrument that scientist use. Thank you :)
