Question

A process in which there is no flow of heat between the system and surroundings is a/an

• A. isochoric process
• B. cyclic process
• C. isobaric process
• D. adiabatic process
• E. isothermal process

Answer 1

The Correct Option is D

The process in which there is no flow of heat between the system and surroundings is known as an adiabatic process. In an adiabatic process, the system does not exchange heat with the surroundings, and any change in internal energy is solely due to the work done by or on the system.

Let's look at the options:

• Adiabatic process: This is the correct answer. There is no heat exchange between the system and its surroundings.
• Cyclic process: The system returns to its initial state. Heat flow may occur during the cycle.
• Isobaric process: Occurs at constant pressure. Heat exchange can occur.
• Isochoric process: Occurs at constant volume. No work is done, but heat exchange is possible.
• Isothermal process: Occurs at constant temperature. Heat is exchanged to maintain temperature.

Therefore, the correct answer is the adiabatic process, as it involves no heat exchange.

Correct Answer:

Correct Answer: (D) adiabatic process
