Question

Which of the following processes is carried out at constant pressure?

• A. Isothermal Process
• B. Isobaric Process
• C. Adiabatic Process
• D. Isochoric Process

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.

Answer 1

The Correct Option is B

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.
