In a physics lab students are conducting an experiment to learn about the heat capacity of different materials. The first group is instructed to add 1.5-g copper pellets at a temperature of 92 degree C to 295 g of water at 16 degree C. A second group is given the same number of 1.5-g pellets as the first group, but these are now aluminum pellets. Assume that no heat is lost to or gained from the surroundings for either group. If the final equilibrium temperature of the copper pellets and water is 26 degree C, how many whole pellets did the first group use in the experiment? The specific heat of copper is 0.0924 kcal/ No heat is exchanged with the surroundings by the system of water and pellets. How is the quantity of heat gained by the cold water related to the quantity of heat lost by the hot pellets? pellets Will the final equilibrium temperature for the second group be higher, lower, or the same as for the first group? The specific heat of aluminum is 0.215 kcal What is the equilibrium temperature of the aluminum and water mixture for the second group?
