What is Third law of thermodynamics?
The '''third law of thermodynamics''' says: *If an object reaches the [[absolute zero]] of [[temperature]] (0 [[Kelvin|K]] = −273.15[[Celcius|C]] = −459.67 °[[Fahrenheit|F]]), its [[atom]]s will stop moving. The [[definition]] is: '''at absolute zero , the entropy of a perfectly crystalline substance is zero'''. Experimentally, it is not possible to obtain −273.15°C, as of now. It is found that most of the gases either liquify or solidify before reaching such a temperature, gaseous molecules no longer remaining. So far, scientists have been able to get close to, but not exactly, absolute zero. This may change in the future. ==Related pages== *[[Zeroth law of thermodynamics]] *[[First law of thermodynamics]] *[[Second law of thermodynamics]] {{physics-stub}} [[Category:Thermodynamics]] [[Category:Laws of physics]]
