Sagot :
The thermal energy of a substance is always related to the physical
state of the substance. Any substance that is in solid state has the least
thermal energy and is in a very stable state. The substance in gaseous form has
the least amount of thermal energy and so it is in a very unstable state. The
substance in liquid form has a medium state of thermal energy. The thermal
energy of liquids fall in between the thermal energy of solids and gases.
