In bomb calorimeter, reactions are carried out at constant:
- volume
- temperature
- pressure
- energy
Explanation
In a bomb calorimeter, reactions are carried out at constant volume.
This is because the calorimeter is designed to keep the volume constant during the reaction.
Any heat released or absorbed during the reaction causes a temperature change, which is measured to determine the heat of the reaction.
The constant volume ensures that the heat measured is solely due to the chemical reaction taking place
Without any external influences like changes in pressure or volume.
