Isolated Thermodynamic System
An isolated thermodynamic system refers to a system that does not exchange energy or matter with its surroundings. In other words, it is a closed system that does not interact with its environment in terms of energy transfer or mass transfer. All the variables within the system, such as energy, mass, and entropy, remain constant over time.
Explanation of the Correct Answer
The correct answer to this question is option 'C', which states that an isolated thermodynamic system has zero energy transfer and zero mass transfer. This means that there is no exchange of energy or mass between the system and its surroundings.
Energy Transfer
When a system is isolated, it means that no energy is transferred across its boundaries. This implies that there are no heat or work interactions occurring between the system and its surroundings. The system remains self-contained and does not gain or lose energy.
Mass Transfer
Similarly, in an isolated system, there is no mass transfer taking place. The system does not allow any matter to enter or leave its boundaries. The total mass of the system remains constant, and there are no interactions with the environment that could cause a change in mass.
Entropy Change
Although not mentioned in the question, it is worth noting that in an isolated system, the entropy remains constant as well. Since entropy is a measure of the system's disorder or randomness, any change in entropy would require an interaction with the surroundings. In an isolated system, where there is no interaction, the entropy remains constant.
Conclusion
In summary, an isolated thermodynamic system is one that does not exchange energy or mass with its surroundings. This results in zero energy transfer and zero mass transfer. The system remains self-contained and its variables, including energy, mass, and entropy, remain constant over time.
