Temperature and Thermal Energy
... Temperature is a property of atoms themselves, and therefore, it does not depend on the number of atoms in an object. Temperature depends only on the average kinetic energy of the particles in the object. Consider two blocks of steel. The first block has a mass of 1 kg, and the second block has a ma ...
