Heat Flow and Energy.
An intensive property of a thermodynamic system is a property that is independent of the system's size or quantity. Examples include temperature, pressure, and density. These properties are useful for comparing and characterizing different systems regardless of their size.
Enthalpy is a thermodynamic property of a thermodynamic system.
The three types of thermodynamic systems are - a) isolated, - b) open, and -c) closed.
You can search the relevant meaning of the availability condition for thermodynamic system in the wikipedia since there's so much to learn and laws of thermodynamic equilibrium that explains what and those condition works.
In a thermodynamic system, the amount of heat that cannot be converted to work is determined by the efficiency of the system. The efficiency is typically less than 100, meaning that some heat will always be lost and cannot be converted to work.
In a thermodynamic process, the work done on a system is equal and opposite to the work done by the system. This is known as the principle of conservation of energy.
Entropy is negative in a thermodynamic system when the system is not in equilibrium and is undergoing a process that decreases its disorder or randomness. This typically occurs when energy is being input into the system to organize or order its components.
When the value of delta S is negative in a thermodynamic system, it signifies that the system is becoming more ordered or losing disorder. This can indicate a decrease in the system's randomness or entropy.
The Joule temperature is a measure of how the energy of a thermodynamic system changes with temperature. It quantifies the relationship between temperature and energy transfer in the system.
please read the 3 kinds of thermodynamic system maybe it can help you to recognize and you can identify which one can be described. http://www.greenserveuk.com/

The change in entropy at constant volume is related to the thermodynamic property of a system because entropy is a measure of the disorder or randomness of a system. When there is a change in entropy at constant volume, it indicates a change in the system's internal energy and the distribution of energy within the system. This change in entropy can provide insights into the system's behavior and its thermodynamic properties.
