Solve the given question:
Question: Calculate the total change in entropy if 3.75 kg of water at 24.7 °C is mixed with another 6.95 kg of water at 74.7 °C. The specific heat of water at constant pressure is 4186 J/(kg•K).
Would you be able to include the how you do it steps and equation and how to follow it thank you!!
