Which outcome occurs when a heat pump using a refrigerant undergoes repeated rapid thermal cycling?

💡 Explanation

Repeated rapid changes cause localized boiling and collapse, leading to cavitation; therefore, cavitation risk increases because of bubble formation, rather than thermal fatigue which happens on longer timescales or viscosity which is less sensitive to thermal cycling.
