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.
When a liquid and a gas are in equilibrium, the rate of evaporation of the liquid equals the rate of condensation of the gas. This means that the vapor pressure of the liquid remains constant over time. Additionally, the temperature of the system remains stable, and both phases coexist under specific conditions of temperature and pressure.
Water boiling to become steam is an example of a liquid to gas phase change.
False. An equilibrium in which all the components are in the same phase (solid, liquid, or gas) is called a homogeneous equilibrium.
When a liquid spreads throughout a gas, it is called evaporation. This occurs when the liquid molecules gain enough kinetic energy to escape into the gas phase. The liquid molecules disperse into the surrounding gas until an equilibrium is reached.
No: Vapor is defined as the gas phase of a substance that is mostly solid or liquid at equilibrium at standard temperature and pressure. Therefore, a liquid itself is never a vapor, but the liquid is in equilibrium with a vapor phase that contains the same chemical substance.
liquid molecules forming a gas and gas molecule forming a liquid are equal in number
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.
Substance at Vapour - Liquid phase equilibrium can exist as both liquid or gas at the same time.
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.
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).
Evaporating and condensing.
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.
When a liquid and a gas are in equilibrium, the rate of evaporation of the liquid equals the rate of condensation of the gas. This means that the vapor pressure of the liquid remains constant over time. Additionally, the temperature of the system remains stable, and both phases coexist under specific conditions of temperature and pressure.
Whe the propelant gas is released from the can the equilibrium gas-liquid is disrupted and more liquid is evaporated.
