What happens in between evaporation and condensation?
Compression is the most important stage happening in a VCC. We know that heat can not pass from low temperature to high temperature. Due to compression Boiling Point of a refrigerant increases above either ambinet temperature or above cooling water temperature and also refrigerant temperature is very high than abmient. Hence heat can flow from refrigerant to atmosphere. This allows sensible cooling first and below BP further high amount of latent heat is removed causing liquification of refrigerant which is not possible unless pressure is raised after evaporator. Hence Compressor is required.
Should refrigerants be operated at temperatures above or below their critical temperature?
The critical temperature of a refrigerant is the point at which it changes states. In a refrigeration scenario, this happens 2 times per cycle. The refrigerant is a liquid on the high pressure side, and below its critical temp. On the low pressure side it becomes a vapor (gas) and its above its crictal temp. So the answer is both, depending on what side of the system you are on.
What happens to temperature above 0 degrees?
Nothing particular happens.
What happens to the temperature of ice when it melts?
Two things could have happened for the ice to melt. The temperature could have gone above 0 degrees. Or a pressure change could have lower the freezing point so that the ice will melt at a temperature where it was frozen.
How is the refrigerant cylinder pressure kept above the system pressure when a system is being charged with vapor from a cylinder?
Add refrigerant vapor on the low side of the system ,the compressor raises the pressure of the refrigerant on the high side of the system and lowers the pressure on the low side

What is the difference between dry steam and wet steam to clean?
DRY steam is superheated There is a temperature below which steam will start to condense into water droplets. This is called the saturation temperature, and it varies with the pressure of the steam. Steam that is exactly at its saturation temperature is called saturated steam. Steam that is below its saturation temperature contains droplets of moisture and is called wet steam. Steam that is above its saturation temperature is called superheated steam.

Is the zone of aeration above the zone of saturation?
Yes, the zone of aeration is above the zone of saturation.
What is the function of superheater?
The function of the super heater is to increase the temperature of the steam above saturation by utilising the heat from the flue gases.
What happens above Curie temperature?
Above the Curie temperature ferromagnetic elements and materials lose this characteristic.
What happens to temperature above 0 degrees?
Nothing particular happens.
Refrigerant condensing temp. should be higher than the exiting water temperature?
As rule of the thumb, refrigerant condensing temperature should between 1-2 degreeC higher than the exiting water temperature, this temperature difference is technically called condensing temperature approach. I f the approach is below or above means, system is flooded with refrigerant or system got starve. Above method is also effective in determining if the condenser shell needs maintenance for sclale, sludge build up removal. I am refrigeration mechanic.
Is the zone of saturation above the zone of aeration?
No. THe zone of saturation is below the zone of aeration.

What happens to temperature above 60 degrees?
There is no reason for anything to happen.
What is the approximate percent saturation of hemoglobin by oxygen in normal arterial blood?
The saturation should be above 90% in normal arterial blood. A totally healthy person will have 95-100% saturation.
