What explains why a sealed calorimeter is a closed system?
A sealed calorimeter is a closed system because it does not exchange matter with its surroundings. This means that no mass enters or leaves the system during an experiment, allowing for accurate measurements of heat transfer.
What is the difference between a closed system and open system chemical reactions?
In a closed system, no matter can enter or leave the system, while in an open system matter can enter or leave the system. This means that closed systems are isolated from their surroundings, while open systems can exchange matter with their surroundings. Chemical reactions that occur in closed systems can potentially reach equilibrium, while those in open systems may continue until one or more reactants are depleted.
Why is it important to determine the q calorimeter before determining the q metal?
Determining the q calorimeter (heat capacity of the calorimeter) is important because it allows for accurate calculations of the heat gained or lost by the calorimeter during an experiment. This value is then used to correct the heat measurements for the system (q metal) being studied, ensuring the heat transfer calculations are precise. Without accounting for the q calorimeter, the heat measurements for the system may be inaccurate.
How can one build a calorimeter?
To build a calorimeter, one can use materials such as a insulated container, a thermometer, a stirrer, and a known heat source. The calorimeter is used to measure the heat released or absorbed during a chemical reaction. By carefully constructing and calibrating the calorimeter, one can accurately determine the heat changes in a system.
Is burning a candle a open or closed system?
Burning a candle is considered an open system. An open system allows for the exchange of matter and energy with its surroundings. In the case of a burning candle, it releases heat and light energy into the surroundings, as well as combustion byproducts like carbon dioxide and water vapor. This exchange of energy and matter with the environment classifies it as an open system.
Which explains why a sealed calorimeter is a closed system?

How do you know that a sealed calorimeter is a closed system?
There is an exothermic reaction that occurs when a closed system exists when using a sealed calorimeter. This exothermic reaction can be identified when energy is being released into the environment.
What explains why a sealed calorimeter is a closed system?
A sealed calorimeter is a closed system because it does not exchange matter with its surroundings. This means that no mass enters or leaves the system during an experiment, allowing for accurate measurements of heat transfer.
Is a burning candle an example of an open system or a closed system?
