How nitrogen in liquid held together?
Liquified by high pressure and/or low temperature.
Why can liquid boil at a low pressure?
Reducing the air pressure allows the molecules to escape
Is Ch4 liquid at low pressure in room temperature?
Of course not,it is not liquid.IT is in gas state
How does the gas propellant move when an aerosol can is used?
From a region of high pressure to a region of low pressure
How is ammonia liquified?
Ammonia is made by haber process. We can turn it to liquid by high pressure and low temperature.
Can pressure alone change something from a solid to a liquid?
in low pressure environments it is possible for a solid to change to a liquid
What is the function of purge in low pressure centrifugal liquid chillers?
funtion of the low pressure control is to pump down compressor in case of low pressure in the system
Why can't liquid boil at a low pressure?
Liquids can boil at low pressure, and in fact do so at lower temperatures than when the pressure is high.
How do you make neon liquid?
high pressure, low temperature.
What state is refrigerant leaving receiver?
low pressure liquid
What color is the symbol for the high pressure system?
red and low pressure is blue
What is low pressure and high pressure in water chiller unit?
In regards to a water chiller unit, the terms low pressure and high pressure refer to the compressor, which takes low pressure and compresses it into high pressure gas, which is then turned into a liquid to cool the unit.
Does refrigerant enter the compressor as a low temperature low pressure gas?
Yes. The basic components of the refrigeration system are the refrigerant, compressor, condenser and receiver, expansion device and the evaporator. One cycle: Refrigerant travels to Compressor (A) to Condenser (B) to Expansion device (C) to evaporator (D). The refrigerant gas at low pressure and temperature is drawn into the compressor. The gas is compressed to a higher pressure, which causes an increase in the temperature. The refrigerant gas at a high pressure and temperature passes to the condenser (point B), where it is cooled (the refrigerant gives up its latent heat) and then condenses to a liquid. The high pressure, low temperature liquid is collected in the receiver. The high pressure liquid is routed through an expansion valve (point C), where it undergoes an abrupt reduction in pressure. That pressure reduction causes part of the liquid to immediately vaporize or flash. The vapor and remaining liquid are cooled to the saturation temperature (boiling point) of the liquid at the reduced pressure. At this point most of the refrigerant is a liquid. The boiling point of the liquid is low, due to the low pressure. When the liquid refrigerant enters the evaporator (point D), it absorbs heat from the process and boils. The refrigerant gas is now at low pressure and temperature, and enters the suction side of the compressor, completing the cycle.
What is low vapor pressure?
Vapor pressure refers to the force exerted by gaseous molecules of a liquid. Usually this is measured in a closed system. For example, in a water bottle some H2O molecules are able to move from liquid to gas phase at room temperature. The molecules that do this create vapor pressure. Low vapor pressure is usually observed in substances that have a low boiling point or if it is being held at a low temperature.
The concentration on of gas in a liquid is directly proportional to its partial pressure in the gas phase above the liquid is known as -------- low?
No answer

Yes, at higher pressure and/or low temperature chlorine is a liquid.
How nitrogen in liquid held together?
Liquified by high pressure and/or low temperature.
