Question

Which type of energy refers to the sum of potential and kinetic energies in the particles of a substance?

Answer 1

Answer:

Thermal energy

Explanation:

Thermal energy is the sum of the kinetic and potential energy of all the particles in an object. The figure shows that if either potential or kinetic energy increases, thermal energy increases.

Answer 2

Answer:

Explanation:

The type of energy that refers to the sum of potential and kinetic energies in the particles of a substance is thermal energy. It is the energy that an object possesses due to the motion of its particles at the atomic and molecular level. When particles move, they possess kinetic energy, and when they interact with each other, they create potential energy. Together, these energies make up the total thermal energy of the substance.

The thermal energy of a substance determines its temperature, and when two objects with different thermal energies come into contact, heat flows from the warmer object to the cooler object until they reach thermal equilibrium, which is when both objects have the same temperature.

Thermal energy is an important concept in many fields of science and engineering, including thermodynamics, materials science, and environmental science. It is used in a wide range of applications, from designing efficient heating and cooling systems to predicting the behavior of materials under different conditions.
