Temperature

Each substance has a different melting point. That depends on what compound you're talking about:

Of table salt, NaCl, it is 801 °C

though of water (ice), H2O, it is 0 °C

and of carbon dioxide it is even lower: -78 °C

About 80-100F is considered hot. I suggest you go to Las Vegas or Honolulu for that weather!

Hot is a relative term. Unlike cold where we have an absolute number (-274oC) below which things cannot get colder as it is absolute zero where all molecular motion ends, the top end of the "hot" scale is open.

We do know that scientists have produced superheated gas exceeding temperatures of 2 billion degrees centigrade. That exceeds the interior of our Sun, which is about 15 million degrees centigrade.

Calculations indicate that within a hundred of a second of the Big bang the temperature of the Universe had cooled to 100 billion degrees centigrade. but earlier than this the temperature was higher.

So the hottest hot can be assumed to be >>100 billion centigrade and the coldest cold -273 degrees centigrade.

This puts us and everything we've ever thought of as being pretty much on the chilly side as far as the overall Universe is concerned.

However hot is a relative term. In our day to day life the hottest thing we are likely to experience directly as the flame of an oxyacetylene torch (3200 °C to 3500 °C). This is hot enough to melt steel. A light bulb filament is about the same temperature by comparison.

We can be badly burnt by much lower temperatures. Anything close to 100o C (the temperature of water) will cause is to suffer cellular injury and potentially death. Hot frypans at 200oC will cause immediate deep burns.

Soups and coffees generally are too hot to drink at 180oC and pizza damages the inside of your mouth about the same temperature.

I am assuming from the question that you want to know about the output from a temperature sensor. While there are some standard types of sensors, the only way to know for certain is to check the specifications for the particular sensor in use. In addition to the specification sheet, the particular sensor will have a calibration factor - the amount it deviates from the standard. That can only be determined by comparing it to a calibrated test source (traceable to known a standard).

Anders Celsius' thermometer works based on the principle that liquids expand when heated and contract when cooled. The mercury or alcohol inside the thermometer rises or falls in a calibrated tube to indicate changes in temperature. Celsius defined the scale so that 0 degrees represents the freezing point of water and 100 degrees represents the boiling point of water.

When temperatures are uniform, it means that they are consistent or evenly distributed across a given space or region. There are no significant variations or fluctuations in temperature throughout the area being observed.

The freezing temperature of water doesn't change. It just has different names.

If you're speaking in Celsius, it's called zero. If you're speaking in Fahrenheit,

it's called 32 degrees.

In January, the coldest month, the summit temperature averages -36° C (-33° F) and can drop as low as -60° C (-76° F). In July, the warmest month, the average summit temperature is -19° C (-2° F). all round the year, no matter how hot it can get, the temperature never rises above freezing. This is the lowest it has ever been.

Relative Humidity can be measured with a psychrometer. A psychrometer has two thermometers, a wet-bulb and dry-bulb. The wet-bulb has a wet cloth on one end. If the wet-bulb is colder than the dry-bulb, than you apply the information to a psychrometer chart, which tells you the relative humidity, from which you can determine "high" or "low".

0 degrees Celsius is freezing, but really water freezes at just BELOW that temperature.

Water in a pot will evaporate at any temperature. The rate of evaporation will increase with the temperature and at some temperature will a stage where steam bubbles form at the bottom of the pot. This depends on the pressure, evenness of the pot and factors other than just the temperature.

The average temperature on Neptune is about -353 degrees Fahrenheit (-214 degrees Celsius). This extreme cold is due to its distance from the sun and its atmosphere primarily composed of hydrogen and helium.

It is theoretically impossible to measure absolute zero temperature, which is 0 Kelvin. At this temperature, all molecular motion stops completely, making conventional temperature measurement methods ineffective.

Between December and February, the average daily temperature can fall as low as 50 degrees.

The process is called simmering. It involves gently cooking food in liquid at a temperature just below boiling, typically around 185-205°F (85-96°C). Simmering helps to cook food evenly and develop complex flavors.

There are different types of jet fuel. Standard ones are Jet A and Jet A-1.

Jet A freezing point = -40 C

Jet A-1 freezing point = -47 C

Google it!

That's the average human body temperature, 98.6F. Celsius (a.k.a. Kelvin) can be converted to Fahrenheit as follows: "C x 1.8 + 32 = F"

=====whoa, whoa. Kelvin is SOOO not Celsius. The formula seems right though.

A thermometer typically measures temperature by detecting the thermal expansion of a substance such as mercury or alcohol. Some specialized thermometers can also measure humidity, pressure, or heat flow.

110 degrees Fahrenheit = 43.3333333 degrees Celsius

In temperature, k typically represents the Kelvin scale, which is an absolute temperature scale where 0K represents absolute zero (-273.15°C or -459.67°F). It is commonly used in scientific measurements and calculations due to its alignment with the behavior of gases.

The most accurate temperature is typically measured using a high-precision digital thermometer with a calibration certificate traceable to a national standard. These thermometers are designed to minimize errors and provide the most precise measurement of temperature.
