A hot copper pipe is placed in a water-filled calorimeter and the calorimeter is sealed. Which pieces of data must you know in order to calculate the thermal energy released as the pipe cools?

Question

Since the calorimeter is sealed, measurement is done in a constant volume (pressure can vary). So you may need the difference in temperature (dT) and heat capacity of water at constant volume(Cv) to calculate the energy thermal energy released.
$$(dE/dT)=Cv$$
$$\Delta E=C _{V}\times \Delta T$$
