On Mars, solids, such as iron, hydrated
(liquid) salts, and carbon dioxide gas, have
been found. Which substance has the most
thermal energy?
Is there a way to increase the thermal energy
of the iron?
When the temperature of an object increases, the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases.
