Physicists have proved a long-suspected quantum speed limit for thermalization, according to the source headline. Thermalization is the process by which an object settles into a stable, even temperature with its environment.
The time required varies with several factors, including the object’s surface area and material properties, as well as airflow. Everyday examples include a car windshield defrosting in winter and a warm drink cooling down.
