Which law states absolute zero cannot be reached?
This would be a consequence of the 2nd law and the "zeroeth" law. Heat always flows from the warmer object to the colder one (2nd law), so to cool something down to absolute zero, you would have to have something colder than absolute zero to absorb the heat coming out. The zeroeth law, however, defines absolute zero as a ground state where energy has been reduced to its absolute minimum - thus you cannot go below absolute zero and thus there cannot be something to absorb the energy to take an object to system down to absolute zero.
What two variables does Charles' law use?
Charles' law relates the volume of a gas to its absolute temperature. V = kT.
Where kirchhoff's law fails?
In semiconductors, at quantum scales, at temperatures close to absolute zero...
Where on earth can you find absolute zero?
Neptune (Pluto was, but it is not a planet anymore. But, absolute zero is unreachable. Absolute zero is the temperature it would be if there was no matter. And since matter is everything, absolute zero is abolutly unreachable.
Why is 273 C is called absolute zero?
It's actually minus 273 which is absolute zero, also known as zero kelvin. This figure was calculated from extrapolation from Charles' Law, one of the three Gas Laws (others are Boyle's Law and the Pressure Law aka Gay-Lussac's Law). Charles' Law states that for a fixed mass of gas at constant pressure, the volume is directly proportional to the temperature; this means that if you have a frictionless container with flexible walls, floor and roof, filled with a certain amount of gas and you then heat that gas, the volume will increase as the temperature rises. If you plot the readings on a simple graph, x-axis temperature, y-axis volume, then the plot will be a straight line which if then continued down below zero Celsius will cross the y-axis and ultimately meet the x-axis at a temperature of -273 degrees; at this point the volume of the gas is theoretically zero because the molecules are not moving at all; there can be no lower temperature than this because the molecules cannot move any less than not at all. Hence -273 C is absolute zero. regards David Bartlett, Basingstoke, Hampshire, UK
In applying Charles' law temperature must be in what scale?
The "Kelvin" scale, which uses the same size of degree as Celsius, but with a zero value at absolute zero. (on the Celsius scale, absolute zero is -273.15° C) There are no negative temperature values on the Kelvin scale.
How can charle's law be used to determine absolute zero?
Charles law is just a theory the government uses to possess our minds and control our future! just kidding really its all about love you know?

What would the volume and pressure of an ideal gas be at absolute zero temperature IF an ideal gas actually existed?
Here's the ideal gas law: PV = nRT If T is zero, then PV must be zero; assuming the volume is nonzero, then for PV to be zero the pressure must be zero. However, this is only true for an ideal gas. For a real gas other factors come into play at low temperatures, and they begin to deviate from the ideal gas law. Also, all real gases liquify above absolute zero, and liquids don't obey the ideal gas law at all.

Charles' law relates the volume of a gas to its absolute temperature. V = kT.
Which law of thermodynamics states that it is impossible to reach absolute zero?
An object can never reach absolute zero in kinetic terms because there is never a total lack of kinetic energy, molecules are always moving.
The impossibility of reaching a temperature of absolute zero is incorporated in?
The Third Law of Thermodynamics."Absolute zero (0 K) is the lower limit of temperature. The temperature of absolute zero cannot be attained physically because to do so would require virtually all the heat to be taken from an object. Therefore, it is impossible to attain a temperature of absolute zero."
When Kelvin predicted Absolute Zero he used Charles' law however in theory this means that a gas at absolute zero has a volume of zero how can this be?
Technically it can't be, since you would be destroying matter and the Law of Conservation of Matter states that matter cannot be created nor destroyed. The theory of absolute theory is just that; theoretical. It was created by the extrapolation of Charle's discoveries about volume and temperature with his balloon experiment, in which the data was extrapolated along a best fit line. If you were to create a method to change something's volume to zero though, let me know, I want to become rich too.

What are the 2 constants in Charles law?
The constants in Charles' Law are pressure and number of moles. The volume of a fixed mass of gas at constant pressure is proportional to its absolute temperature.
What is law formulated by Jacques Charles?
It is simply called Charles' Law. The law that Charles formulated maintains that under constant pressure the volume of an ideal gas is proportional to the absolute temperature. The volume of a gas at constant pressure increases linearly with the absolute temperature of the gas. The formula is V1/T1=V2/T2See link below.
What is the significance of the intercept of the graph for charles's law?
The intercept of -273¤C on the Charles law graph represents the absolute minimum of temperature below which it is not possible to go -Chukwuma Akubueze
