Identify the process that proceeds with no heat exchange between system and surrounding.
- AIsothermal
- BIsobaric
- CIsochoric
- Correct answerDAdiabatic
Solution
An adiabatic process is defined as a thermodynamic process in which there is no heat exchange between the system and its surroundings. In this process, $q = 0$.
An isothermal process occurs at constant temperature ($\Delta T = 0$).
An isobaric process occurs at constant pressure ($\Delta P = 0$).
An isochoric process occurs at constant volume ($\Delta V = 0$).
Answer: Adiabatic
An isothermal process occurs at constant temperature ($\Delta T = 0$).
An isobaric process occurs at constant pressure ($\Delta P = 0$).
An isochoric process occurs at constant volume ($\Delta V = 0$).
Answer: Adiabatic
Hence, the correct answer is option: 'D'.
