In an equilibrium between a liquid and a gas, the rate of evaporation equals the rate of condensation. This means that molecules are transitioning between the liquid and gas phases at the same rate, resulting in a stable system.

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.
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 are the phase changes processes taking place when a substance is in equilibrium between liquid and gas phase?
Evaporating and condensing
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.
Is it true or false that the temp. at which a liquid turns to a gas is called the boiling point?
True. The temperature at which a liquid turns into a gas is called the boiling point.
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.
Can be a liquid or gas?
Substance at Vapour - Liquid phase equilibrium can exist as both liquid or gas at the same time.
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 an example of the liquid to gas change equilibrium?
Evaporating and condensing.
What temperature is sature?
Saturated gas temperature is the temperature at which a gas would be in equilibrium with the liquid phase of the gas (or with the liquid phase of a component of the gas if it was a gas mixture).
What is the temperature at which a liquid and gaseous phases are in equilibrium?
The temperature at which a liquid and gas are in equilibrium is called the boiling point. At this temperature, the vapor pressure of the liquid equals the atmospheric pressure, allowing the liquid to change into gas and vice versa at a constant rate.
How does gas propellant move when an aerosol can is used?
Whe the propelant gas is released from the can the equilibrium gas-liquid is disrupted and more liquid is evaporated.
What is an example of the liquid-gas phase-change equilibrium?
Evaporating and condensing.
What is an example of the liquid-to-gas phase change Equilibrium?
Evaporating and condensing.
What are the phase changes processes taking place when a substance is in equilibrium between liquid and gas phase?
Evaporating and condensing
What is saturated gas temperature?
Saturated gas temperature refers to the temperature at which a gas is at its saturation point, meaning it is in equilibrium with its liquid phase (saturated vapor). This temperature is specific to each gas and is often used in thermodynamics to analyze phase changes.
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.
