Problem

At thermal equilibrium between two objects in direct contact, which of the following statements is correct? a)

\text{The particles in both objects stop moving entirely.}

\text{The particles in both objects possess the same average kinetic energy.}

\text{Both objects now contain the same amount of thermal energy (heat).}

\text{The hotter object still has greater average kinetic energy, but no net heat is transferred.}
