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.

Is a burning candle an example of an opened system or a closed system?

A burning candle is an example of an open system because it exchanges both energy (in the form of heat and light) and mass (as the candle wax burns) with its surroundings.


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.


When a candle burns wax undergoes a combustion reaction would a candle burn longer in the open or when covered with an inverted glass jar?

The candle burning in the open will burn longer, because it has easy access to oxygen to sustain the reaction. The flame of the candle burning under the jar will go out quickly, since it will use up its available oxygen faster than the oxygen can be replenished. Even if the jar is open at the bottom, the heat, carbon monoxide, and carbon dioxide produced by the flame will prevent sufficient oxygen from getting to the flame to feed it.


Is a Acid Rainfall open system or closed system?

Acid rainfall is considered an open system because it involves the interaction of the atmosphere, biosphere, and lithosphere. The pollutants that cause acid rain come from various sources and can be transported over long distances by wind, making it a system that is not contained within a specific boundary.


How do you use sulfur Candles?

You place the candle in a pan of water and light the wick. Remove all food and pets from the area and seal up the rooms. You should use one candle per room. The burning will create sulfur gas. When this gas comes in contact with water, it creates sulfuric acid which will kill all insects, because of the water in their bodies. After about 8 hours, you can return and open up the windows to let the rooms air out.
