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
When the evaporation rate equals the condensation rate the space above the liquid is?
When the evaporation rate equals the condensation rate, the space above the liquid is in a state of dynamic equilibrium, where molecules are constantly transitioning between the liquid and gas phases but there is no overall change in concentration.
Does water move in equilibrium?
In equilibrium, the movement of water is balanced, with the rate of evaporation equal to the rate of condensation. This state occurs when the vapor pressure of water in the air is equal to the vapor pressure of water in the liquid.
What statement best describes liquid water and water vapor at equilibrium?
At equilibrium, liquid water and water vapor coexist at a specific temperature and pressure, where the rate of evaporation of the liquid equals the rate of condensation of the vapor. This dynamic balance means that the amount of water in both phases remains constant over time, despite the continuous molecular exchanges. The vapor pressure of the water is determined by the temperature, and at equilibrium, it reflects the tendency of water molecules to escape into the vapor phase versus returning to the liquid phase.
What is true of a liquid and a gas are in equilibrium?
When a liquid and a gas are in equilibrium, their rates of evaporation and condensation are equal, resulting in a stable system where the amount of liquid and gas remains constant over time. At this point, the vapor pressure of the gas is in balance with the pressure exerted by the liquid. This equilibrium is influenced by temperature and pressure; any changes can shift the balance, leading to more evaporation or condensation. Additionally, this state is fundamental in understanding phase transitions and properties of substances.
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?

What is the gas pressure above a liquid at equilibrium called?
The gas pressure above a liquid at equilibrium is called the vapor pressure. This is the pressure at which the rate of evaporation equals the rate of condensation, leading to a dynamic equilibrium between the liquid and its vapor.
What is the temperature at which the rate of evaporation equals the rate of condensation?
The temperature at which the rate of evaporation equals the rate of condensation is known as the equilibrium vapor pressure. At this temperature, the vapor pressure of a liquid is equal to the external pressure, leading to a dynamic equilibrium between the liquid and vapor phases.
When the evaporation rate equals the condensation rate the space above the liquid is?
When the evaporation rate equals the condensation rate, the space above the liquid is in a state of dynamic equilibrium, where molecules are constantly transitioning between the liquid and gas phases but there is no overall change in concentration.
What is true about the rate of evaporation in a dynamic equilibrium between the liquid state and the gas state?
It Occurs as water moleclues absorb energy and it also occurs at the surface of liqud.
What are the phase change processes taking place when a substance is in equlibrium between liquid and gas phase?
During equilibrium between liquid and gas phases, the substance undergoes both evaporation (liquid to gas) and condensation (gas to liquid) processes simultaneously. The rate of evaporation equals the rate of condensation, leading to no net change in the amount of liquid or gas over time. This dynamic equilibrium is maintained as long as the system's temperature and pressure remain constant.
What are the phase changes processes taking place when a substance is in equilibrium between liquid and gas phase?
Evaporating and condensing
What is true if a liquid and gas are equilibrium?
If a liquid and gas are in equilibrium, it means that the rate of evaporation is equal to the rate of condensation. This indicates that the system has reached a balance between the liquid and gas phases with no net change in the amount of substance transitioning between the phases.
Is it true the rates of evaporation and condensation are equal at equilibrium?
Yes, at equilibrium the rates of evaporation and condensation are equal. This means that the liquid and gas phases reach a balance where molecules are transitioning between the two states at an equal rate.
What is dynamic equilibrium Describe what is happening to the liquid and vapor at the boundary of a liquid that is in dynamic equilibrium Is the overall balance of liquid and vapor changing?
1. Dynamic equilibrium is when the rate of vapour and liquid being produced has stabilized, and stopped changing. It's called dynamic equilibrium because the liquid hasn't stopped changing into vapour, and the vapour hasn't stopped changing into liquid, but the rates of these two changes has stabilized so that there is a constant amount of liquid and vapour present.2. At the boundary of the liquid, particles with sufficient energy break away from the liquid and become vapours, and vapour molecules with low energy, or those that make contact with the surface of the liquid, become bonded to the liquid. There is a constant exchange of particles, hence dynamicequilibrium3. No, the overall balance of liquid is constant, hence equilibrium.
What is true if a liquid and a gas are in equilibrium?
liquid molecules forming a gas and gas molecule forming a liquid are equal in number
Does water move in equilibrium?
In equilibrium, the movement of water is balanced, with the rate of evaporation equal to the rate of condensation. This state occurs when the vapor pressure of water in the air is equal to the vapor pressure of water in the liquid.
