What is thermal energy?(1 point)
Responses
the distance between particles and their freedom to move around
the distance between particles and their freedom to move around
the measurement of energy in an object due to position, conduction, or chemical composition
the measurement of energy in an object due to position, conduction, or chemical composition
a material that is a conductor of heat
a material that is a conductor of heat
the total kinetic energy of all particles in a substance
I think it is B

I apologize for the confusion, but the correct answer is:
the total kinetic energy of all particles in a substance.
the total kinetic energy of all particles in a substance.
