More sophisticated bomb calorimeters are built for use at constant volumes.
A bomb calorimeter is only approximately adiabatic. In reality, there is a small heat leak through the dewar (q calorimeter ¹ 0) and the stirrer does work on the calorimeter (w calorimeter ¹ 0). Nonadiabaticity is corrected for with an empirical radiative correction, RC.

A coffee cup calorimeter is essentially a polystyrene (Styrofoam) cup or two with a lid. The coffee cup calorimeter is operated at constant pressure (ambient pressure). The cup is partially filled with a known volume of water and a sensitive thermometer is inserted through the lid of the cup so that its bulb is below the water surface. Rx3 cyclone.
