Which of the following best defines the condition of thermal equilibrium between two systems in thermal contact?
(a) The systems have the same internal energy, so no energy can be transferred between them.
(b) The systems have the same temperature, so there is no net energy transfer between them.
(c) The systems possess identical heat capacities, eliminating any possible net energy transfer.
(d) The systems are in the same phase (solid, liquid, or gas), preventing energy exchange.
