Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Heat is associated with Thermal energy, which in turn is related to Kinetic energy of oscillation of particles. When you remove heat from a system, you are basically decreasing Kinetic energy of oscillating particles. Now what is entropy? it is the measure of randomness. what does it mean by randomness? it means rapidity of movement of particles. Now you can relate. when heat is taken out, particles will begin to move less rapidly. Thus the entropy decreases. Hope this will help. Best regards.
