Question
What is thermal energy?(1 point)
Responses
the total kinetic energy of all particles in a substance
the total kinetic energy of all particles in a substance
a material that is a conductor of heat
a material that is a conductor of heat
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
To find the answer to this question, we need to understand what measure reflects the average kinetic energy of particles in a substance.
The average kinetic energy of particles in a substance is related to the concept of temperature. Temperature is a measure of the average kinetic energy of particles. So, the correct option is "temperature."
Therefore, the answer to the question is "temperature."
