Question

the total kinetic energy (measured in calories) of all the particles in a substance is referred to as

Explanation:

• Polarity refers to the separation of electric charge leading to a molecule having a dipole. It is not related to the total kinetic energy of particles.
• Temperature is the average kinetic energy of the particles in a substance. It is not the total kinetic energy.
• Heat is defined as the total kinetic energy of all the particles in a substance and is measured in calories (or other energy units like joules).

Answer:

heat
