This question tests fundamental definitions in thermodynamics. Understanding the basic terminology related to a thermodynamic system is crucial for solving problems and understanding concepts in this field.
Correct Option: D) System
This question tests fundamental thermodynamic definitions. We need to understand the basic components of a thermodynamic study: the system, its surroundings, and what encompasses both.
D) Universe. The universe, in a thermodynamic sense, is defined as the system plus its surroundings. It represents the complete extent of what is being analyzed or considered in a thermodynamic process.
The question asks to identify the type of thermodynamic system that allows the exchange of both matter and energy with its surroundings. Understanding the definitions of different thermodynamic systems is key to answering this question.
B) Open system
An open system is defined as a system that can exchange both matter and energy with its surroundings. Examples include an open cup of coffee (exchanges heat and water vapor) or a living organism.
A) Closed system — A closed system allows the exchange of energy (heat and work) but not matter with its surroundings. For example, a sealed container of gas can be heated or cooled, but no gas escapes or enters.
C) Adiabatic system — An adiabatic system is a special type of closed system where no heat exchange occurs with the surroundings. It can still exchange work. It is perfectly insulated. An example is a perfectly insulated thermos flask, though in reality, perfect adiabatic systems are idealizations.
D) Isolated system — An isolated system is the most restrictive type. It does not allow the exchange of either matter or energy with its surroundings. The universe itself is often considered an isolated system. A perfectly sealed and insulated container would approximate an isolated system.
The question asks to identify the type of thermodynamic system that allows the exchange of energy but not matter with its surroundings. Understanding the definitions of different thermodynamic systems is key to answering this question.
Correct Option: A) A closed system is defined as a thermodynamic system that can exchange energy (e.g., heat or work) but not matter with its surroundings. An example is a sealed container (like a pressure cooker with its lid on) heating up on a stove; heat can enter the system, but no steam (matter) escapes.
The question asks to identify the type of thermodynamic system that cannot exchange either matter or energy with its surroundings. This requires understanding the definitions of different types of thermodynamic systems based on their interaction with the surroundings.
Correct Option: C) An isolated system is defined as a thermodynamic system that can exchange neither matter nor energy with its surroundings. A perfectly insulated and sealed container would approximate an isolated system.
The question asks to identify the type of wall that allows heat transfer between a system and its surroundings. This is a fundamental concept in thermodynamics related to the properties of boundaries.
Correct Option: C) A diathermic wall is a wall that allows heat to pass through it, facilitating thermal interaction between the system and its surroundings. Examples include metallic containers.
