🤓 Based on our data, we think this question is relevant for Professor Turnpenny & Murphy's class at BU.
Recall: The change in internal energy (ΔE) is given by:
A bomb calorimeter measures heat at constant volume. At constant volume, w = 0 which means:
Mothballs are composed primarily of the hydrocarbon naphthalene (C10H8). When 1.025 g of naphthalene is burned in a bomb calorimeter, the temperature rises from 24.25°C to 32.33°C. Find ΔErxn for the combustion of naphthalene. The heat capacity of the calorimeter, determined in a separate experiment, is 5.11 kJ/°C.
