Question

3. A 4.00 gram sample of solid gold was heated from 274K to 314K. How much energy was involved?
Heat Capacity of Gold is 0.129J/g°C

Answer 1

Q = mcΔT = (4.00 g)(0.129 J/g•°C)(40.85 °C - 0.85 °C)
Q = 20.6 J of energy was involved (more specifically, 20.6 J of heat energy was absorbed from the surroundings by the sample of solid gold).
