What does AC compressor do?
Cycles refrigerant through the system and changes the state of the refrigerant from a low pressure vapor to a high pressure vapor.
What is the best definition of condensation?
Condensation is the process by which a gas or vapor changes into a liquid state due to a decrease in temperature or an increase in pressure. It is the opposite of evaporation, where a liquid changes into a gaseous state.
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 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.
The temperature at which the vapor pressure of a liquid is equal to the external pressure is?
The temperature at which the vapor pressure of a liquid equals the external pressure is called the boiling point. This is when the liquid changes into vapor at a constant temperature.
What is sub cooled vapor?
Subcooled vapor refers to a vapor that is at a temperature lower than its saturation temperature at a given pressure. In other words, it is a vapor that is in a superheated state but exists at a temperature below its boiling point at the current pressure. Subcooled vapor is not in equilibrium with its liquid state and is considered to be in a superheated state.
How can water change from liquid into a vapor and back again?
Water changes from liquid to vapor through the process of evaporation when it gains enough energy to break free from its liquid state. The process reverses when the vapor loses energy, condenses, and returns to a liquid state, known as condensation. These changes in state are influenced by factors such as temperature and pressure.
What state of change is sublimation?
Sublimation is a phase transition where a substance changes directly from a solid to a gas without passing through the liquid state. This process occurs when the vapor pressure of the solid exceeds the atmospheric pressure.
What changes a high pressure vapor to a high pressure liquid?
Cooling the high pressure vapor to lower its temperature and increase its density can cause it to condense and change into a high pressure liquid.
What physical changes does water?
water undergoes from solid state to liquid state at 0oC and from liquid state to gaseous [e.g. vapor, steam] state at boiling temp. 100oC provided the pressure is atmospheric: 1 ATM
What is it when water changes to water vapor?
When water changes to water vapor, it has changed its state from liquid to vapor and no chemical change has taken place. It's only a physical change.
What state is refrigerant entering the compressor?
Low pressure vapor
