Photosynthesis is an open system because energy enters the system and mass both enters and leaves the system. In very general terms photosynthesis is:
carbon dioxide + water + light ==> oxygen + plant growth
The exact process is a bit more complex, but the gist of it is that it is open because both mass and energy cross the boundaries of the system if the system is identified as the plant.

Can there be a limit to entropy in a closed system?
In a closed system, entropy will tend to increase or stay constant over time due to the second law of thermodynamics. This means that there is no limit to entropy in a closed system, as it will continue to increase until reaching equilibrium.
Is the amount of disorder or useless energy in a system?
Entropy is a measure of the amount of disorder or useless energy in a system. It is a concept in thermodynamics that quantifies the randomness and unpredictability of a system. Entropy tends to increase over time in a closed system, leading to increased disorder.
What are closed and open system?
Closed systems exchange energy but not matter with their surroundings, while open systems exchange both energy and matter. An example of a closed system is a sealed container of gas, where heat can be transferred in or out but no gas can escape. In contrast, a boiling pot of water is an open system, as it allows steam to escape while heat is continuously added. Understanding these systems is crucial in fields like thermodynamics and environmental science.
What is the first law of thermodynamics applied to closed and open system showing the meaning of the positive and negative sign of heat and work?
The first law of thermodynamics states that: "The internal energy of a system is a function of its state. Any increase in the internal energy of a system is equal to the sum of the heat supplied to the system and the work done on the system." In equations, this is stated as: DU = DQ + DW where DU is the INCREASE in internal energy DQ is the heat SUPPLIED DW is the work done ON the system So, if heat is lost by the system, it means that DQ is negative and if work is done by the system, it means that DW is negative. The best way to answer thermodynamics questions involving the first law is to think logically about what calculations should be made. If you do this, you will never make mistakes about signs.
What is the system plus it's surroundings?
In thermodynamics, a system refers to the specific portion of matter or space under study, while the surroundings encompass everything outside that system that can exchange energy or matter with it. The system can be classified as open, closed, or isolated based on its ability to exchange energy and matter with the surroundings. Understanding the interactions between a system and its surroundings is crucial for analyzing energy transfers, chemical reactions, and physical processes. This relationship helps in applying the laws of thermodynamics to real-world scenarios.
In thermodynamics a closed system is a system where?
In thermodynamics, a closed system is a system in which no mass can enter or leave the system, but energy can be transferred in the form of heat or work. This means that the total mass of the system remains constant over time, but energy can be exchanged with the surroundings.
Is a snow leopards circulatory system opened or closed?
closed
Does entropy always increase in a closed system?
Yes, entropy always increases in a closed system according to the second law of thermodynamics.
What is a closed system in thermodynamics?
A thermodynamically closed system is one where no mass enters or leaves the system. That does not preclude the possibility of heat or work entering or leaving the system.
What are the characteristics of a closed system?
A closed system does not require contact and interaction with the environment in order to survive, this could also be considered a characteristic. A closed system could also be referred to as an isolated system in thermodynamics.
Is a rabbit an example of a closed system or opened system?
open
What is the difference between opened and closed system of air conditioning?
A closed system would be full of freon without any leaks and a opened system would have no freon or has leaks...........
What are the two ways in which the second law of thermodynamics is verified?
in a closed system and with simple engines and machines
What is the basic things of thermodynamics?
The First Law of Thermodynamics is the conservation of energy. You can't create energy, nor destroy it; the total amount of energy in a closed system remains constant.The First Law of Thermodynamics is the conservation of energy.

How does entropy work in the context of thermodynamics and the second law of thermodynamics?
Entropy is a measure of disorder or randomness in a system. In the context of thermodynamics and the second law of thermodynamics, entropy tends to increase over time in isolated systems. This means that energy tends to disperse and become less organized, leading to a decrease in the system's ability to do work. The second law of thermodynamics states that the total entropy of a closed system will always increase or remain constant, but never decrease.
What is difference between open system and closed system in thermodynamics?
A system which can exchange mass as well as matter with the surroundings is called anopen system.Example:- Heating of CaCo3 in an open bulb.A system which can exchange energy but not matter is called a closed system.Example:- Calcination of CaCo3 in a sealed bulb.
Is the respiratory system opened or closed?
All respiratory systems are open as the function of a respiratory system is to exchange gases with inside of the body and the external world. The term 'open' or 'closed' refers to the vascular system.
