What occurs at thermal equilibrium? a. heat flows from the higher-temperature substance to the lower-temperature substance. b. heat flows from the lower-temperature substance to the higher-temperature substance. c. heat does not flow because both substances are at the same temperature.

C. Equilibrium means at an equal or same state; the two substances have reached thermal equilibrium, so they are at an equal state of temperature. No energy is transferred.

C, JUST TOOK

Explanation:

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.
