A bomb calorimeter measures heat flow at a constant volume, as you can imagine a bomb as a rigid chamber that cannot increase in volume. A polystyrene cup calorimeter on the other hand measured changes in temperature at a constant pressure.
The polystyrene calorimeter is an open system. heat can leave. But a bomb calorimeter is closed and isolated
Wouldn't a regular polystyrene calorimeter be an approximation of a closed system, because heat can go out but volume remains the same?
