← ScienceWhich failure results when pressure exceeds Van der Waals force limits holding refrigerant R-134a molecules together?
A)Compressor motor coil insulation breakdown
B)Refrigerant phase change to plasma
C)System's lowered coefficient of performance
D)Complete system's runaway over-pressure✓
💡 Explanation
At high pressure, the increased kinetic energy overcomes intermolecular attraction; causing disruptive expansion. Therefore, loss of intermolecular force, rather than motor failure, leads to runaway pressure because the refrigerant rapidly vaporizes rather than experiencing efficient compression.
