The kinetic energy within molecules of an object when heat is added

As an object is heated up, its atoms and molecules move and collide faster. Geothermal energy is the thermal energy in the earth. Wind ... total kinetic energy of the particles hat make up a substance.

Answer: Increases

Explanation: As we know from the kinetic theory of gases that the kinetic energy is directly proportional to the temperature and temperature is directly proportional to the velocity of the molecule.

Thus when the heat is added in the system, temperature gets increases which in turn will increase the velocity of the molecule and these molecules will collide even faster.

Thus kinetic energy within the molecule of an object increases when the heat is added to the system.
