Question

What is true for two pieces of iron at the same temperature that are different mass?

A) The average kinetic energy of their particles is different.
B) Heat flows from the larger object to the smaller object.
C) The total thermal energy of their particles is different.
D) Heat flows from the smaller object to the larger object.

Answer 1

C) The total thermal energy of the particles in each piece of iron will be different, because the total energy of a substance is proportional to its mass. However, if they are at the same temperature, their average thermal energy per particle will be the same.

Answer 2

Their particles have the same total kinetic energy.

Step-by-step explanation:

Their particles have the same total kinetic energy.
