How is absolute zero originally determined?

Answer 1

The volume of gases decreases with temperature; extrapolating the volume/temperature relationship, it looked as if all gases would reach a volume of zero at approximately the same temperature, about minus 273 degrees centigrade.

Answer 3

Absolute zero, the lowest possible temperature at which particles cease to move, was first determined by scientist Lord Kelvin in the 19th century. Kelvin extrapolated the behavior of gases as they approach this temperature using the ideal gas law and thermodynamic principles. The concept of absolute zero is crucial for understanding the behavior of matter at extreme cold temperatures.

Answer 4

The value of absolute zero is the temperature at which all molecules and atoms stop moving completely.
