Answer is: B.) Yes, if work is done, this transfer process can take place.

For example,  air conditioner involves a cyclic process that transfers heat from a cold reservoir to a hot reservoir, but with use of electricity.

Thermal conductuction is the transfer of heat through physical contact. Thermal conduction is the transfer of heat by microscopic collisions of particles. Heat spontaneously flows from a hotter to a colder body.

The process of heat conduction depends on four basic factors: the temperature gradient, the cross section of the materials involved, their path length and the properties of those materials.

Yes, it is very possible, if work is done, transferring heat from a cold reservoir to a hot reservoir can take place. This implies the correct answer is B.

A good example, in this case, is an air conditioner. Air conditional entails a cyclist process in which heat is transferred from a cold reservoir to a hot reservoir using electricity. Also, in the process of heat transfer, the air conditioner generates more heat.

Further Explanation

The transfer of heat in this case is via thermal conduction. It involves the transfer of heat by collisions of particles microscopically. It also involves electrons movement in a body.

The collided particles such as atoms, electrons, and molecules transfer microscopic kinetic and potential energy that is disorganized.

However, the disorganized potential energy and microscopic kinetic are together known as internal energy.  

In other words, heat transfer through conduction involves direct contact between molecules and atoms.

The process of heat transfer via conduction simply depends on the four major factors:

  • The temperature gradient
  • The cross-sections of the materials involved in the process
  • The path length of the material involved
  • The conductive properties of the materials involved
  • Therefore, it is very possible, if work is done to transfer heat from a cold reservoir to a hot reservoir
