Which of the following occurs during heat transfer between a hotter body and a colder body? thermal energy of the hotter body decreases and kinetic energy of the hotter body increases. thermal energy is absorbed by the colder body and the average kinetic energy of its particles increases. the colder body transfers thermal energy to the hotter body and the average kinetic energy of the colder body particles decreases. the transfer of thermal energy creates friction which warms both objects and increases the kinetic energy of their particles.

Option (b) is the correct answer.

Explanation:

Thermal energy is defined as the energy present within a system due to the kinetic energy of its particles.

So, when heat is transferred from a hotter body to a colder body then thermal energy of hotter body will be absorbed by colder body. This will lead to increase in average kinetic energy of colder body until a thermal equilibrium is maintained between both the bodies.

Hence, we can conclude that when heat transfer between a hotter body and a colder body then thermal energy is absorbed by the colder body and the average kinetic energy of its particles increases.

i believe the answer is a.
