The molecules in a steel bar absorb energy and begin moving more quickly. What's most likely happening to the steel bar?

Respuesta :

The steel bar is most likely being heated, because the heat is increasing the kinetic energy of the molecules, making them move faster.

Hope this helps!

What gives energy to the particles is heat, if the particles receive heat they will move faster, so the steel bar is exposed to heat.
