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 surroundings
But practically surroundings of a system is the neighborhood of the system which can interact with the system.
Types of systems:
1. Open System
An 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 System
A 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 System
In 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.

Is entropy closely related to the 1st law of thermodynamics?
Entropy is closely related to the 2nd law of thermodynamics, not the 1st law. The 1st law of thermodynamics states that energy cannot be created or destroyed, only transferred or converted. Entropy, on the other hand, is a measure of the disorder or randomness of a system, which increases over time according to the 2nd law of thermodynamics.

What is the relationship between entropy and multiplicity in the context of thermodynamics?
In thermodynamics, entropy and multiplicity are related concepts. Entropy is a measure of the disorder or randomness in a system, while multiplicity refers to the number of ways a system can be arranged while still maintaining the same overall energy. In simple terms, as the multiplicity of a system increases, so does its entropy. This relationship is important in understanding the behavior of systems in thermodynamics.
What law of thermodynamics is unavailable for doing work?
"Unavailable for doing work" is related to the Second Law of Thermodynamics.

L. Peusner has written: 'The principles of network thermodynamics' -- subject(s): Biophysics, Linear systems, System analysis, Thermodynamics 'Concepts in bioenergetics' -- subject(s): Bioenergetics, Biophysics, Thermodynamics 'Studies in network thermodynamics' -- subject(s): System analysis, Thermodynamics
How is the 1st law of thermodynamics related to the conservation of energy?
By the first law of thermodynamics, energy is conserved - i.e. the sum of the useful work and the energy lost to heat will equal the energy you started with. The second law states that you will never get 100% energy efficiency.
Which law is entropy closely related to?
Entropy is closely related to the second law of thermodynamics, which states that the entropy of a closed system will always remain the same or increase over time, but never decrease. This law describes the tendency of systems to move towards a state of maximum disorder or randomness.
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 the relationship between the first law of thermodynamics and the law of conservation of energy?
The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or converted. This is directly related to the law of conservation of energy, which states that the total energy in a closed system remains constant. In essence, the first law of thermodynamics is a specific application of the broader principle of conservation of energy.
Why is it required for students to be excellent in math in order to do thermodynamics?
Thermodynamics is a part of physics, and physics is very closely related to maths. Physics involves a lot of mathematical equations and problems, and as such, to be good in thermodynamics, you have to be good in maths.
What does the term "negative enthalpy" signify in the context of thermodynamics and how does it impact the overall energy of a system?
In thermodynamics, "negative enthalpy" indicates that a system has released heat energy. This can lower the overall energy of the system, making it more stable.
How is flow energy related to thermodynamics?
Flow energy is related to thermodynamics through the concept of energy conversion and conservation. In thermodynamics, flow energy refers to the energy associated with the movement of fluids or gases. This energy can be converted into other forms of energy, such as mechanical work or heat, according to the laws of thermodynamics. The conservation of energy principle in thermodynamics states that energy cannot be created or destroyed, only transferred or converted from one form to another. Therefore, understanding flow energy is crucial in analyzing and predicting the behavior of systems in thermodynamics.
