Please explain the concept of temperatres of absolute zero.?

Answer 1

Here is the idea behind temperature of an object.

Objects have molecules and the more the molecules (or just atoms) vibrate the hotter the object is. As they vibrate, they move and have kinetic energy, which in this form is what you think of as heat energy. (We make a distinction because heat energy is too randomly oriented to use, kinetic energy is not). The more they vibrate the hotter the object is.

That was just background to get you to where you can understand absolute zero.

Absolute zero is where the molecules aren't vibrating at all. It is absolute in the sense that you can't move less than not moving at all and thus it is impossible to reach a lower temperature.

Just as a point of interest: This vibrating is also roughly why things expand when they get hot. The net affect of all the molecules making it up are vibrating more vigorously, causes them to push against eachother harder causing a net expansion.

Answer 2

Temperature is the measure of the average kinetic energy held by a body. This energy is represented in the molecular movement of the particles within the area or mass.

Heat in the air, as we typically think of it, is the result of the air molecules vibrating faster than they do if the air is cool. In fact, coldness itself isn't an entity, it is merely the absence or lessened presence of heat/molecular vibration. This vibration energy can be transferred from particle to particle when particles are near eachother and interract, or it can diffuse as liquid molecules spread outward.

Absolute zero is the point at which the molecule stops vibrating, however this point is impossible to reach in reality. We can only come very very close. It is called absolute zero because once the molecule has stopped, it can't slow down anymore, and thusly can't lose anymore heat. You can't be any slower than stopped, that point, which is again impossible to attain is called absolute zero.

Answer 3

It is the coldest you can get an object.
In the ideal gas law
PV=nRT
Where P is pressure
V is volume
n is number of moles of gas
R is a constant
T is temperature
Absolute zero is the temperature at which an ideal gas has zero pressure or volume (you pick)

OR
In Air or any gas molecules are moving around and colliding into each other. In a solid or liquid they are vibrating.
At absolute zero Air molecules have no kinetic energy, solids and liquids have no vibrational energy.

Answer 4

At absolute zero, the only energy left in a physical system is the zero point energy. Quantum mechanical rules (the Pauli exclusion principle) won't let more than one fermion occupy the same physical state, and keeping them apart means that some residual (spin) energy must exist even at absolute zero.

Answer 5

Absolute zero is 460 degrees F below 0 degrees F. The point at wich molecules stop moving.

Answer 6

Actually absolute zero is only a theoretical point calculated from existing experimental trends. When all energy sources cease to cause changes in the material.

I believe the closest they came was with liquid He, check google for more info.

Answer 7

It's amazing you Americans quote absolute zero in fahrenheit when the Kelvin scale, on which absolute zero is ZERO, steps in the same units as the Centigrade scale.

Absolute zero is -273 centigrade (actually 272.6, I believe).

Just so you know, Americans are the only people in the world who cling on to the silly fahrenheit scale.

Answer 8

Absolute Zero, -450 F or 0 degrees Kelvin, is the total absence of heat. There is no molecular activity at this temperature. Basically, EVERYTHING is frozen.

Answer 9

Absolute zero is the lowest possible temperature. There is no movement, no kenetic energy, all matter is frozen including electrons, etc..

Answer 10

concept? well its about minus 450 F but im not sure that there is a concept behind it, it just is, and thats darn cold. its the temp at which nothing can survive.
