8- Lead pellets, each of mass 1.40 g, are heated to 200°C. How many pellets must be added to 511 g of water that is initially at 20.0°C to make the equilibrium temperature 25.0°C?Neglect any energy transfer to or from the container.
9-A student drops two metallic objects into a 120-g steel container holding 150 g of water at 25°C. One object is a 164-g cube of copper that is initially at 87°C, and the other is a chunk of aluminum that is initially at 5.0°C. To the surprise of the student, the water reaches a final temperature of 25°C, precisely where it started. What is the mass of the aluminum chunk?
