Which outcome occurs when refrigerants in an air conditioning system undergo a phase change in the evaporator coil?

💡 Explanation

When liquid refrigerant evaporates in the coil, the system undergoes a phase change because it absorbs latent heat from the surrounding air, providing cooling. Therefore, heat absorption is how incoming air cools, rather than increased pressure, dropped viscosity or increased density, none of which represent typical cooling methods.
