Question

Which statement is true for two pieces of iron at the same temperature?

1.Responses The average kinetic energy of their particles is the same. The average kinetic energy of their particles is the same.
2.Heat flows from the object with higher potential energy to the object with lower potential energy.
3.Heat flows from the object with higher potential energy to the object with lower potential energy.
4.Heat flows from the larger object to the smaller object. Heat flows from the larger object to the smaller object. The total kinetic energy of their particles is equal.

Answer 1

1

Step-by-step explanation:

when two pieces of substances are in thermal equilibrium, this means the amount of heat flowing in one substances is equal to the amount of heat flowing from it. The temperature of the substance is related to the kinetic energy of the molecules.
