Question:
Which of the following processes is carried out at constant pressure?
Which of the following processes is carried out at constant pressure?
Show Hint
Keep in mind that in an isobaric process the pressure remains constant, whereas in an isothermal process the temperature remains constant. Isochoric processes involve constant volume, and no heat exchange occurs in adiabatic processes.

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
An isobaric process occurs when the pressure of a system remains constant, even as volume and temperature change. Examples include:
• Heating or cooling of a gas in a piston-cylinder setup.
• Phase changes at constant atmospheric pressure.
Other processes:
• Isothermal: Constant temperature.
• Adiabatic: No heat exchange.
• Isochoric: Constant volume.
