Can I Have An Example Of A Closed System??
Please use easy words that I can understand, Im not that smart and i'm only in 7th grade.
Also can you give me an example of an Open System??
Thank You.
Okay lets give this a try.
Imagine that you have a kennel and a small dog. Lets think about the kennel as the system and the dog as our energy source inside the kennel. The dog has a mass of, lets say 5kg. You lock the kennel with the dog in it. Another dog comes along and he wants to play with the dog that you locked in the kennel. The other dog also has a mass of 5kg. Since the dog can not leave the kennel, the system is called a closed system because the dog's mass that is already inside the kennel can not leave and the dog that is outside the kennel can not enter. Since mass can not be transfered, meaning the dogs can not enter or leave the system (kennel), the system is a closed system. Now imagine that you remove the door and the lock form the kennel. Since both dogs can enter and leave as they chose, the system (the kennel) is called an open system because mass can transfer inside and outside the system.
I hope this helps.
Oh! And this is 7th grade science so please don't make it difficult for me to understand.
Thanks Again.
thank you very much for your help.
Of course! I'll be glad to explain it to you.
A closed system is a system that does not allow the transfer of matter or energy with its surroundings. In simpler terms, it means that nothing can enter or exit the system. An example of a closed system could be a jar full of water, tightly sealed with a lid. The water and the jar together form a closed system because no water can go in or out, and no energy is exchanged with the surroundings.
Now, an open system is the opposite. It allows the transfer of matter and energy between the system and its surroundings. One example of an open system is a classroom. Air can flow in and out of the classroom, students can come and go, and the teacher can bring in teaching materials. All these interactions with the surroundings make it an open system.
I hope that helps! Let me know if you have any more questions.
