3) A block of copper of unknown mass has an initial temperature of 65.4 °C. The copper is immersed in a beaker containing 95.7 g of water at 22.7 °C. When the two substances reach thermal equilibrium, the final temperature is 24.2 °C. What is the mass of the copper block? Cs for Copper = 0.385 J/g.C Cs for H20 = 4.184 J/g.C q H2O = 600.6 J q Cu = -600.6 J

Cs for Copper = 0.385 J/g.C Cs for H20 = 4.184 J/g.C q H2O = 600.6 J q Cu = -600.6 J 4) Which of the following (with specific heat capacity provided) would show the smallest temperature change upon gaining 200.0 J of heat? Explain your answer based on the specific heat capacity value. Specific Heat (J/g°C) 0.903 J/g°C 0.385 J/g°C 0.79 J/g°C 0.128 J/g°C 0.235 J/g°C Substance Amount in Grams 50.0 g 50.0 g 25.0 g 25.0 g Al Cu Granite Au Ag 25.0 g 5) A 70.0-g piece of metal at 80.0 °C is placed in 100 g of water at 22.0 °C contained in a calorimeter. The metal and water come to the same temperature at 24.6 °C. How much heat did the metal give up to the water? What is the specific heat of the metal?
