What Is a Refrigerator Evaporator; Why Is It Important?

What Is a Refrigerator Evaporator; Why Is It Important?

Jan 12, 2021 The refrigerator evaporator is one part of the refrigeration cycle that makes the inside of your refrigerator cold. After the refrigerant gas has gone through the condenser coils located at the back of the refrigerator, it starts to cool down and turn into a liquid. It’s at this liquid stage that the refrigerant reaches the expansion valve.

Does water evaporate faster than other liquids?

Does water evaporate faster than other liquids?

May 21, 2020 4.3/5 (2,155 Views . 18 Votes) A liquid with weaker intermolecular attractions will evaporate faster. Intermolecular attractions make liquids more cohesive so that individual molecules must have more energy to escape. Because of this water has a higher surface tension and more energy is required for water molecules to escape the liquid phase.

Q A: why salt doesn't evaporate - Department of Physics

No. (As a minor point, the atomic weight of O is 16, not 8, and Na is 23, not 11.) The real reason is that the Na + would have much higher energy as an isolated ion than it has surrounded by water molecules. That's largely an electrostatic effect, since the H 2 O's mostly point their negative O's toward the positive Na +.Once the water gets scarce, the Na + starts to join up …
