Absolute zero is the temperature at which all atoms practically stop moving (technically the atoms may still move, but they don't have enough energy to transfer their own movement on to the next atom). Because a gas is made up of atoms which move, the gas will become a solid when it reaches absolute zero (becuase the atoms in solids don't move).

What is the third law of thermodynamics as defined by Ludwig Boltzmann?
"As a system approaches absolute zero, all processes cease and the entropy of the system approaches a minimum value.""it is impossible by any procedure, no matter how idealised, to reduce any system to the absolute zero of temperature in a finite number of operations".Lewis (of Lewis acids and bases fame) and Merle Randall phrased it as"If the entropy of each element in some (perfect) crystalline state be taken as zero at the absolute zero of temperature, every substance has a finite positive entropy; but at the absolute zero of temperature the entropy may become zero, and does so become in the case of perfect crystalline substances."
What is the 3 law of thermodynamics?
There is no accepted or established "fourth law of thermodynamics". There are, however, numerous authors who have postulated versions of fourth laws to explain certain aberrant phenomena. The following link gives over fifteen different versions of postulated "fourth" laws of thermodynamics: http://www.humanthermodynamics.com/4th-Law-Variations.html
What is a Vacuum in kilo pascal?
Depends on If it's absolute or relative. Vacuum in any unit is zero in absolute pressure. Vacuum in any unit is -normal air pressure in relative pressure.
Why is absolute zero only expressed in Kelvin and not celsius?
Because on the Celsius (aka Centigrade) scale, zero is defined as the freezing point of water at standard pressure. On the Kelvin ( aka absolute ) scale zero is defined as the lowest temperature possible - not relative to water or any other substance.
Do any objects have no friction at all?
No. All materials have the slightest bit of friction. Even if an object may look smooth to the human eye, it has a microscopic jagged side. Even something as smooth as ice has a little friction
How can you determine if an object is not at absolute zero when observing it?
When observing an object, you can determine if it is not at absolute zero by looking for any signs of movement, such as vibrations or changes in temperature. Objects at absolute zero would not exhibit any movement or show any signs of heat.
Can absolute value be zero?
The absolute value of zero is zero. The absolute value of any other real number - or even of any other complex number - is different from zero.
Can an absolute value be zero?
The absolute value of zero is zero. The absolute value of any other real number - or even of any other complex number - is different from zero.
What is absolute value minus absolute value?
Zero. The absolute value |n| is positive for any real number. Subtracting it from itself is zero.
Why is it theorized that the coldest obtainable temperature cannot be any colder that absolute zero?
The third law of thermodynamics states that as a system approaches absolute zero, its entropy approaches a minimum value. At absolute zero, the system would be in a state of perfect order, and any further decrease in temperature would result in negative temperatures with higher entropy, violating the laws of thermodynamics. Thus, it is theorized that absolute zero is the lowest temperature possible.
How can you interpet comparison involving absolute value?
the absolute value of any number of spaces it if from zero
When does enthalpy become zero?
Enthalpy can be zero for a pure substance at its standard state, where it is defined as the enthalpy of formation. This typically occurs at a reference temperature and pressure specified for the substance.
What is the name for the at which a temperature can't get any colder?
absolute zero
Is there any system which works below 0 Kelvin temperature?
No. Zero Kelvin is absolute zero.
What type of energy does any object above absolute zero give off?
Any object above absolute zero gives off thermal energy in the form of heat radiation.
No more energy can be removed from matter at?
at the dead state or zero state. it is the state of matter which is equivalent to the state of surroundings
According to the kinetic theory of matter what do particles of matter do when the temperature is absolute zero?
The particles on every state of matter are always in motion, and hence will have a specific amount of kinetic energy both related to their temperature and current state. Solids move less than liquids, liquids less than gasses, etc. At absolute zero, it's theorized that independant molecular movement within any state of matter would cease, and that matter would therefore have no kinetic energy other than being physically moved somewhere by an outside force.
