Understanding PV Diagrams and Isobaric Processes

What does the 'P' in a PV Diagram stand for?

• Potential

• Power

• Pressure

• Position

If a piston moves up, what happens to the volume in a PV Diagram?

• Volume remains constant

• Volume decreases

• Volume becomes zero

• Volume increases

What happens to the pressure if the piston is pushed down quickly?

• Pressure decreases

• Pressure becomes zero

• Pressure increases

• Pressure remains constant

Which of the following is a characteristic of an isobaric process?

• Constant energy

• Constant pressure

• Constant temperature

• Constant volume

Which of the following is NOT a thermodynamic process commonly represented on a PV Diagram?

• Isothermal

• Isotonic

• Isobaric

• Adiabatic

In an isobaric process, how is the work done by the gas represented on a PV Diagram?

• Area under a vertical line

• Area under a horizontal line

• Area under a diagonal line

• Area under a curve

What does the area under the curve in a PV Diagram represent?

• Volume change

• Pressure change

• Work done

• Temperature change

What is the significance of the area under the curve in an isobaric process?

• It represents the change in volume

• It represents the work done by or on the gas

• It represents the change in temperature

• It represents the change in pressure

In an isobaric process, what happens if the volume increases?

• Work is done by the gas

• Pressure decreases

• Work is done on the gas

• No work is done

How can you ensure constant pressure in an isobaric process in a lab?

• By fixing the piston

• By allowing the piston to move freely

• By increasing the temperature

• By decreasing the volume
