A 100 g lead ball at a temperature of 100â—¦C isimmersed in 300 g of water with the temperature 20â—¦C contained inan insulated boiler whose heat capacity can be neglected. What willbe the mixing temperature? What entropy change does the ballproduce? What entropy change does the water bring?What will be thetotal entropy change?
A 0.10 kg heavy steel ball with a temperature of 200â—¦Cis thrown into a lake with temperatures 20â—¦C. Which is the entropychange for the ball, for the sea and for the whole system(universe)
