At which temperature does the motion of atoms and molecules stop?

asked in Physics by anonymous

1 Answer

  1. Absolute zero is where all atomic and molecular motion stops and is the lowest temperature possible. Absolute Zero occurs at 0 degrees kelvin  or -273.15 degrees Celsius or at -460 degrees Fahrenheit. All objects emit thermal energy or heat unless they have a temperature of absolute zero.
