Which of the following factors would not affect the vapor pressure of a liquid?
The surface area does not affect the vapor pressure since the pressure is force per area which means it just adjust to the area.
What is the vapour pressure of a liquid?
The vapor pressure of a liquid is the point at which equilibrium pressure is reached, in a closed container, between molecules leaving the liquid and going into the gaseous phase and molecules leaving the gaseous phase and entering the liquid phase.
Which of the factors below affect the equilibrium vapor pressure of a liquid in a container?
The factors that affect the vapor pressure of any particular liquid are: The temperature – the higher the temperature, the greater the vapor pressure. nothing else – for example, air does not “hold” water vapor in it to form humidity.
Which of the following does not affect vapor pressure?
Surface Area: the surface area of the solid or liquid in contact with the gas has no effect on the vapor pressure. Types of Molecules: the types of molecules that make up a solid or liquid determine its vapor pressure.
Which of the following factors affect the pressure?
Temperature, pressure, volume and the amount of a gas influence its pressure.
How does water vapour affect air pressure?
Answer: As humidity increases pressure decreases. Since water vapor is less dense than dry air if both have the same temperature, the addition of water vapor decreases the overall density of the air and lowers its pressure.
How does temperature affect vapour pressure of a liquid?
As the temperature of a liquid increases, the kinetic energy of its molecules also increases and as the kinetic energy of the molecules increases, the number of molecules transitioning into a vapor also increases, thereby increasing the vapor pressure.
What causes vapour pressure?
Vapor pressure is dependent upon temperature. When the liquid in a closed container is heated, more molecules escape the liquid phase and evaporate. The greater number of vapor molecules strike the container walls more frequently, resulting in an increase in pressure.
Does pressure affect vapor pressure?
The vapor pressure is hardly influenced by the atmospheric pressure in that regard, because we ignore the intermolecular forces in ideal vapors.
Which of the following factors affect the vapor pressure of a liquid quizlet?
Intermolecular forces and temperature are the only factors that affect vapor pressure. For a given liquid, temperature is the only factor.
What causes vapor pressure to increase?
As the temperature of a liquid increases, the kinetic energy of its molecules also increases. As the kinetic energy of the molecules increases, the number of molecules transitioning into a vapor also increases, thereby increasing the vapor pressure.
What are the three factors that affect the liquid pressure?
Factors affecting a pressure in a liquid
- Density of liquid (ρ)
- Depth of liquid (h)
- Acceleration due to gravity (g)
What are the factors on which vapour pressure depends?
There are four factors on which vapour pressure depends. They are: Nature of liquid is explained on the basis of its intermolecular forces. That is, as the magnitude of the intermolecular forces increases vapour pressure will decrease. As the temperature of the liquid increases the kinetic energy associated with the liquid also increases.
How do you increase the vapour pressure of a liquid?
Heating the molecules of the liquid can help change them to the vapour phase and thus increase the vapour pressure of the liquid. For example, Acetone and benzene have higher vapour pressure than water at a particular temperature. 2. Effect of temperature The vapour pressure of the liquid increases with an increase in its temperature.
Does vapor pressure increase or decrease with temperature?
Conversely, vapor pressure decreases as the temperature decreases. The vapor pressure of a liquid can be measured in a variety of ways. A simple measurement involves injecting a little of the liquid into a closed flask connected to a manometer.
How does surface area affect vapor pressure?
The pressure exerted by the gas in equilibrium with a solid or liquid in a closed container at a given temperature is called the vapor pressure. Surface Area: the surface area of the solid or liquid in contact with the gas has no effect on the vapor pressure.
