Prompt: How can entropy be reversed?

Reply: There is no single answer to this question as entropy is a thermodynamic property and therefore its reversal depends on the specific system under consideration. In general, however, entropy can be reversed by either increasing the temperature of the system (thus increasing the average kinetic energy of the particles) or by decreasing the volume of the system (thus increasing the number of collisions between particles).
