Which statement is incorrect? Internal energy is the sum of the energies of all the individual particles in a particular sample of matter. If the Kelvin temperature is doubled, the average kinetic energy is also doubled. Kinetic molecular theory is related to the total molecular kinetic energy. Heat can be considered the energy transferred between objects with different temperatures. If a system absorbs energy, its internal energy increases.
