Thermal transpiration, also known as thermal creep, is a phenomenon related to the motion of gas molecules in a system where there is a temperature gradient. It occurs when gas molecules in a confined space or small tube move from a region of higher temperature to a region of lower temperature. This movement is influenced by the kinetic energy of the gas molecules, which is greater in the hotter region.
