When vapor pressure equals atmospheric pressure at the surface of a liquid it has reached its what?
When the vapor pressure equals atmospheric pressure at the surface of a liquid, it has reached its boiling point. This is the temperature at which the vapor pressure of the liquid is equal to the pressure exerted on it by the surrounding atmosphere, causing the liquid to change into vapor.
What is the relationship between the rate of evaporation and the rate of condensation of the vapor of a liquid in a closed container and has a constant vapor pressure?
In a system at constant vapor pressure, a dynamic equilibrium exists between the vapor and the liquid. The system is in equilibrium because the rate of evaporation of liquid equals the rate of condensation of vapor. -KarkatHorns
Is true vapor pressure absolute pressure?
No, true vapor pressure is the pressure exerted by a vapor in equilibrium with its condensed phase at a given temperature. Absolute pressure refers to the total pressure within a system, including atmospheric pressure. These two concepts are related but not the same.
Is refrigerant leaving a compressor in a cars air conditioning system high pressure vapor high pressure liquid or low pressure vapor?
Refrigerant leaving a compressor in a car's air conditioning system is a high pressure, high temperature vapor. This vapor carries heat energy away from the evaporator coil inside the car, allowing the refrigerant to absorb heat from the cabin air and cool it down before circulating it back.
When recharging a refrigeration system with R-11 what vapor pressure is necessary in the shells before charging with liquid?
The vapor pressure in the system's shells should be equal to the saturation pressure of the refrigerant at the temperature at which the system is being charged. This ensures that the refrigerant enters the system in a liquid state to prevent damage from excessive liquid refrigerant entering the compressor. It is important to follow the manufacturer's recommendations for proper charging procedures when working with refrigerants like R-11.
In an open system is the vapor pressuse equal to the outside air pressure?
In an open system, the vapor pressure of a substance can be influenced by factors such as temperature and the presence of other gases. The vapor pressure will tend to reach equilibrium with the surrounding air pressure, but may not always be equal due to various environmental conditions.
When a liquid is boiling its vapor pressure and the room pressure are this is called?
When a liquid is boiling, its vapor pressure is equal to the atmospheric pressure in the room. This is called equilibrium.
What is crude oil true vapor pressure?
True Vapor Pressure is the pressure of the vapor in equilibrium with the liquid at 100 F (it is equal to the bubble point pressure at 100 F)
The temperature at which the vapor pressure of a liquid is equal to the external pressure is the what?
The temperature at which the vapor pressure of a liquid is equal to the external pressure is known as the boiling point. At this point, the liquid changes to a gas by overcoming the external pressure.
What is boiling in matter?
Phase shift from liquid to gas (vapor), where the vapor pressure is just equal to the atmospheric pressure.
How does the observed process in the jar relate to the vapor pressure of the system?
The observed process in the jar is related to the vapor pressure of the system because as the liquid evaporates and turns into vapor, it increases the pressure inside the jar. This is because the vapor molecules exert pressure on the walls of the container, leading to an increase in vapor pressure.
What Is true pressure?
True Vapor Pressure is the pressure of the vapor in equilibrium with the liquid at 100 F (it is equal to the bubble point pressure at 100 F).
What term defines the temperature at which the vapor pressure of the liquid equals the atmospheric pressure?
The temperature at which the vapor pressure of the liquid equals the atmospheric pressure is called THE BOILING POINT.
What is equilibrium vapor pressure?
It is vapor molecules in equilibrium with a liquid in a closed system exert a pressure proportional to the concentration of molecules in the vapor state.
What is a example of air pressure?
an example of air pressure would be 45% of water vapor outside.
What component of a refrigeration system changes a high pressure vapor to a high pressure liquid?
The condenser is the component of a refrigeration system that changes high-pressure vapor into high-pressure liquid by transferring heat to the surrounding environment. This process involves the conversion of refrigerant from a gas to a liquid state by releasing heat to the outside air or water.
How is the refrigerant cylinder pressure kept above the system pressure when a system is being charged with vapor from the 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
