Question

Silver pellets with a mass of 1.0 g and a temperature of 81 ∘C are added to 260 g of water at 18 ∘C.

A.) How many pellets must be added to increase the equilibrium temperature of the system to 30 ∘C? Assume no heat is exchanged with the surroundings.

B.) Find the number of copper pellets that are required.

Answer 1

Answer #1

Heat gained by silver + Heat gained by water = 0 (Heat is lost by the silver and heat gained by the water)
