At which temperature does all molecular motion stop?
The point at which all molecular motion stops is called absolute zero. Absolute zero is defined as 0 Kelvin or approximately -273.15 degrees Celsius. At this temperature, molecules have the minimum possible amount of energy and their motion comes to a standstill. It is important to note that achieving absolute zero is not practically possible, as it would require the removal of all heat from a substance. However, scientists have been able to reach extremely low temperatures very close to absolute zero, allowing them to study the behavior of matter at such extreme conditions.
