Answer:

It cools down

Explanation:

The expansion valve lowers down the pressure of the refrigerant (in liquid form). This allows the refrigerant to expand. As the refrigerant expands the heated molecules in it get spread to a larger area and thus the oscillatory vibrations in the molecules get reduced there by reducing the kinetic energy ( KE )and thus the heat. Also sometimes spray of Aerosols are used to cool down the refrigerant.

Which object can electrically polarized

kobusy [5.1K]

Answer:Static electricity works because objects which are otherwise "neutral" (in other words, objects with no net charge) can be polarized. An electric field, like one caused by a nearby charged object, can cause the charges inside of a neutral object — the protons and electrons — to move around a tiny bit.
