Temperature?

Question

some one answered a Q on here a few days ago and from that i learnt that temperature isn't what i thought it was
it is the measurement of hot to cold
or something very similar
could you please without using long big words and complicated phyics exsplain it more please
and how it comes around
p.s i understand some stuff

thanks

Mr IP

Answer 1

This was all started one day by Mr. David Fahrenheit. He wanted to figure out how hot things were, and realized the need for a standardized way to measure things. Then he put a thermometer in his lab assistant's mouth, and marked that as 100 °F (turns out with 98.6 °F as "normal", the assistant probably had a fever that day). Then to get a "zero" he mixed ice, salt, and water. He kept adding more and more salt to make it colder. The solution stabilizes at 0 °F, and so that was where it all came from.

To "correct" this odd set of numbers, along came Anders Celsius, who didn't like funny numbers, and so he put 0 °C as the point at which ice melts, and 100 °C for when water boils.

Today, we base temperature more on standard properties that everyone can agree are the same. Absolute zero (−459.67 °F) is the point at which atoms have the least possible amount of energy. They form a Bose-Einstein condensate, where all the molecules dog-pile on top of one another. They only just figured out how to do this 12 years ago, and they guys who did it won the Nobel Prize.

To sum up: temperature is a measure of the random "moving around" energy the molecules have, and their ability to break free and move around. The hotter you get is because things have more energy and move faster, and hit things harder.

Answer 2

The temperature of a mass is an indication of its thermal energy, which is directly related to the average speed of vibration of it's constituent particles (if the mass is solid) or the average speed of the particles freely whizzing about (in the case of fluids).

The actual thermal content of the mass also depends on its mass and its specific thermal capacity. This means that 2 masses having the same temperature do not necessarily contain the same amount of energy.

The other important thing about temperature is that thermal energy can only pass from a body at a higher temperature to a body at a lower temperature (provided no external work is done on the system, like in a fridge).

Answer 3

Actually it's a measurement of hot, but not cold. Every body (object) contains a certain amount of "heat", the more the higher it's temperature. When that "heat" is completely absent its temperature is 0 K (K=Kelvin, it's the physical unit of measurement for temperature), and it can't be lower than that. Since there's no such physical thing as "coldness" it can't go lower than 0, either there's some heat in it or there isn't.

Answer 4

Temperature is a measure of heat intensity, 'How Hot or How Cold' a substance is and can be measured by a thermometer. It's the addition or removal of Sensible Heat (Can be sensed or, felt) which changes temperature.

Heat however is the AMOUNT of Heat Energy involved with 'Sensible' or 'Latent Heat'. ('Latent' means 'Hidden', it cannot be measured by a thermometer, only by calorimetry or calculation),
Latent Heat however, will only change the 'State' of a substance with NO change in temperature...Solid to Liquid and vice-versa or Liquid to Vapour and vice-versa'.

Answer 5

Temperature is the number that tells the level of heat energy in a material, a room or something.

There is a law in nature that make heat energy to leave volumes of high temperature and get into volumes of lower temperature. When temperature is even the energy stream stops.
The number temperature,t, give the speed of energy transport. This number called temperature has other properties, but this is the most usual use of the word temperature.

Answer 6

Temperature has made up values - we just said - temp water boils at... make that 100, freezing point = 0 degrees.
That is the way centigrade works
Fahrenheit was meant to be 200 to 0 but was totally messed up.
It ended up 32 freezing, and 212 boiling - 180 divisions in between.

Answer 7

Temperature is a physical property of a system that underlies the common notions of hot and cold; something that is hotter generally has the greater temperature.

Answer 8

how hot or cold a matter is.
is that ok 4 u dude?

Answer 9

Hey dude! i just got your email... sorry i havent gotten to reply yet... BUT I WILL!

And yes... it is hot and cold...
