A cup of tea can be considered an open system because it exchanges both energy and matter with its surroundings. For example, steam can escape from the cup (matter), and heat can be lost to the air (energy). If the cup were covered, it would be more of a closed system, allowing only energy exchange but no matter exchange. However, in most practical scenarios, a cup of tea is typically open.
The system is open.
In thermodynamics, a system is that part of the universe which is under experimental study or observation. The surroundings constitute everything other than system. That is The universe = The system + The surroundingsBut practically surroundings of a system is the neighborhood of the system which can interact with the system.Types of systems:1. Open SystemAn open system can exchange both energy and matter with the surroundings.Eg: Hot water kept open in cup. Here both matter (steam) and energy (heat) is exchanged with the surroundings by the system.2. Closed SystemA closed system can exchange energy but not matter with the surroundings.Eg: Hot water kept closed in a cup. Exchange of only heat takes place.3. Isolated SystemIn an isolated system, exchange of matter as well as energy is not possible.Eg: Hot water kept in a thermos flask. Exchange of steam as well as heat does not takes place.
The fuel sample in the open cup is exposed to air,thereby decreasing it's vapor pressure when compared to the same in a closed cup.
there is always a bomcalimeter... What like hydraulics? A closed system is one that cannot be influenced or freely entered by just any source. The systems in the human body are considered to be closed systems. Closed systems are completely apart from the outside environment and only have interaction within the system. Some examples of a closed system are machine bureaucracy, production line, specific departments and corporate messaging. A closed system is a theoretical construct, much like a circle or a straight line. No real-world examples exist. However there are multiple systems, in practice, which behave much like a closed system. A basic example is a cup of water covered in plastic wrap, or anything suspended in a vacuum.

No, it wasn't.
The competition is now closed.

Replace with a new cup holder assembly. It's $173. Ouch.
