Atoms move around and collide with the thermometer and exchange its energy causing the thermometer to go up.. Three units of measuring temperature. Most natural events involve a decrease in total energy and an increase in disorder.. The energy that was “lost” was converted to heat. . An increase in energy/motion decreases the overall order (organization) of the system..
