They are inversely related. The volatility of a liquid increases with decreasing vapor pressure, as it provides more reversible effect on liquid molecules, so less liquid molecules are able to escape. Conversely, the volatility of liquid increases with decreasing vapor pressure, as it provides less reversible effect on liquid molecules, allowing more to escape.

Polarity of a substance affects its intermolecular forces, which in turn impacts its vapor pressure. Generally, polar molecules have stronger intermolecular forces compared to nonpolar molecules, leading to lower vapor pressure. This is because polar molecules are less likely to escape into the gas phase due to their stronger intermolecular attractions.

∙ 12y agoThe higher the polarity of a molecule, the stronger the inter molecular attractions between the molecules. This means less of the liquid will change into gas (less vapor) and there is greater attraction (less expansion). Therefore, a higher polarity means a lower vapor pressure.

Is the vapor pressure of a liquid a linear function of temperature?
No, the vapor pressure of a liquid is not a linear function of temperature. It follows the Clausius-Clapeyron equation, which is an exponential relationship between vapor pressure and temperature. As temperature increases, the vapor pressure of a liquid typically increases exponentially.
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 equilibrium vapor pressure?
Equilibrium vapor pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) in a closed system at a specific temperature. It represents the balance between molecules escaping from the condensed phase and re-entering it.
What does the vapor pressure of water at 10 C compare with its vapor pressure at 50 C?
At higher temperature the vapor pressure is higher.
What is the approximate vapor pressure when the gas condenses at 80oC?
The vapor pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature. The vapor pressure depends on the temperature and the substance.
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

What is difference between vapor pressure and vapor density?
I do not now
What is the relationship between pressure and the boiling points of liquid?
As atmospheric pressure increase so does the boiling pont, when atmos. pressure decreases so does boiling point. A liquid boils when its vapor pressure equals atmospheric pressure.
What is the relationship between water vapor and altitude?
as altitude inscreases, water vapor level decreases
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 relationship between the temperature and dew point?
Dew point is the temperature at which the water vapor in the air condenses, then evaporates. The barometric or air pressure is independent from the dew point.
What are the significance of Clausius-Clapeyron equation?
The Clausius-Clapeyron equation is significant because it describes the relationship between temperature and vapor pressure during phase transitions. It helps in understanding how the equilibrium between different phases of a substance changes with temperature. Additionally, it is used to predict the behavior of substances undergoing phase changes, such as evaporation or condensation.
What is equilibrium vapor pressure?
Equilibrium vapor pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) in a closed system at a specific temperature. It represents the balance between molecules escaping from the condensed phase and re-entering it.
Explain how the attractive forces between the particles in a liquid and the equilibrium vapor pressure of that liquid related?
The weaker the intermolecular forces, the easier the liquid evaporates. Higher vapor pressure the faster it evaporates. Thus, the weaker the attractive forces, the higher the vapor pressure and vice versa.
What does the vapor pressure of water at 10 C compare with its vapor pressure at 50 C?
At higher temperature the vapor pressure is higher.
What is the relationship between molecular mass and vapour density?
The relationship between molecular mass and vapor density is that they are proportional to each other. Vapor density is defined as the mass of a vapor relative to the mass of an equal volume of air, while molecular mass is the mass of a molecule of a substance. Therefore, a higher molecular mass will result in a higher vapor density.
