A 25.0g sample of copper at 363 K is placed in 100g of water at 293 K. The copper and water come to same temperature via heat transfer from copper to water. Calculate final temperature of the water.
Molar heat capacity of copper = 24.5 J*(K^-1)*(mol^-1) and that of water = 75.2 J*(K^-1)*(mol^-1).
A 24.0 g copper ring at 0.000°C has an inner diameter of D = 2.54000 cm. An aluminum sphere at 103.0°C has a diameter of d = 2.54508 cm. What is the mass of the sphere
