Thermodynamics: Reversible and Irreversible Processes

Which of the following is an example of an irreversible process?

• Boiling an egg

• Melting ice into water

• Water freezing into ice

• Compressing a gas slowly

What is a key characteristic of reversible processes?

• They occur spontaneously.

• They leave no trace on the system or surroundings.

• They cannot be reversed.

• They happen at a finite rate.

Why are irreversible processes more challenging to calculate?

• They involve constant temperature changes.

• They require complex equipment.

• They occur too slowly.

• They do not follow equilibrium conditions.

In an isothermal reversible expansion, what remains constant?

• Pressure

• Volume

• Number of moles

• Temperature

What is the formula for the work done by an ideal gas during isothermal reversible expansion?

• P * ΔV

• -nRT * ln(Vf/Vi)

• nC_v * ΔT

• nRT * (Vf - Vi)
