Calculate Silver pellets with a mass of 1.0 g and a temperature of 85 °C are added to 220 g of water at 14 degrees * C . (a) How many pellets must be added to increase the equilibrium temperature of the system to 25 °C? Assume no heat is exchanged with the surroundings. (b) If copper pellets are used instead, does the required number of pellets increase , decrease, or stay the same? Explain. (c) Find the number of copper pellets that are required .
