How to solve examples on entropy of a thermodynamic system - SPPU paper solutions

This video explains how to solve examples on entropy of a thermodynamic system. This example is taken from MAY 2018 question paper of Thermodynamics of Savitribai Phule Pune University (S.P.P.U.) The problem statement is as follows: A copper block of mass 1 kg at 500K is immersed in a lake of 300 K till it reaches thermal equilibrium with water. Find the : 1) Total heat transferred to the lake 2) Change in entropy of the lake 3) Change in entropy of copper (Cp of copper = 0.386 kJ/kgK, Cp of water = 4.187 kJ/kgK).
