Is a bomb calorimeter a closed system
WebA device used for experimental determination of heat change in the system is called a calorimeter (bomb calorimeter), a closed container with a thermometer to measure the initial and final water temperature.. Energy is measured in units of Calories (cal). 1cal is the amount of energy required to increase the temperature of 1g of water by 1 o C or 1K.. … WebBecause it allows heat to be exchanged, a bomb calorimeter is a closed system. While this system is insulated, it is not one of the three main types of systems: closed, open, or isolated. Is a calorimeter also an isolated system? Coffee calorimeters are isolated (except if they have a lid that prevents gas from escaping) ...
