Question

what is temperature equilibrium? when particles of matter have reached an equal temperature the flow of energy from one particle to another when some particles of matter are moving faster than others

Explanation:

Temperature equilibrium occurs when there is no net heat transfer between objects. This happens when the particles of matter have reached an equal temperature. The second option correctly describes this state. The third option describes heat transfer (not equilibrium), and the fourth option describes a non - equilibrium state (faster - moving particles mean a temperature difference).

Answer:

When particles of matter have reached an equal temperature
