Question

What is true for two pieces of iron at the same temperature

Answer 1

The average kinetic energy of their particles is the same

Step-by-step explanation:

The temperature of an object/substance is directly related to the average kinetic energy of the particles in the object, according to:

`E_K = (3)/(2)kT`

where

`E_K` is the average kinetic energy of the particles

k is the Boltzmann's constant

T is the temperature of the object

Since k is the constant value, from the equation we see that if two objects of same nature have same temperature T, then the average kinetic energy of their particles, Ek, is the same.
