How does vapor pressure of water at 50 oC compare with its vapor pressure at 50 oC?
The saturated vapor pressure of water at 50 oC is 123,39 mm Hg.
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 normal boiling point and vapor pressure of a substance?
The normal boiling point of a substance is the temperature at which its vapor pressure equals the atmospheric pressure. In other words, the higher the vapor pressure of a substance, the lower its normal boiling point will be.
Is vapour pressure intensive property?
Yes, vapor pressure is an intensive property because it does not depend on the amount of substance present. It is characteristic of the specific substance at a given temperature and does not change with the quantity of the substance.
How can one determine the boiling point from vapor pressure?
To determine the boiling point from vapor pressure, one can use the Clausius-Clapeyron equation, which relates the vapor pressure of a substance to its temperature. By plotting the natural logarithm of the vapor pressure against the reciprocal of the temperature, the boiling point can be determined as the temperature at which the vapor pressure equals the atmospheric pressure.
How does vapor pressure of water at 50 oC compare with its vapor pressure at 50 oC?
The saturated vapor pressure of water at 50 oC is 123,39 mm Hg.
Is vapor pressure chemicals property or chemical property?
Vapor pressure is a physical property of a substance, not a chemical property. It refers to the pressure exerted by a vapor in equilibrium with its liquid or solid phase at a given temperature. This property is influenced by factors such as temperature and intermolecular forces, and it does not involve a change in the chemical composition of the substance.
How can one determine the actual vapor pressure of a substance?
To determine the actual vapor pressure of a substance, one can use a device called a vapor pressure thermometer. This device measures the pressure exerted by the vapor of the substance at a specific temperature. By comparing the vapor pressure readings at different temperatures, one can determine the actual vapor pressure of the substance.
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.
Does vapor pressure of a substance increase with increased temperature?
Yes, the vapor pressure of a substance generally increases with increased temperature. This is because higher temperatures provide more energy to the molecules of the substance, allowing more of them to escape and form vapor.
What is the relationship between the normal boiling point and vapor pressure of a substance?
The normal boiling point of a substance is the temperature at which its vapor pressure equals the atmospheric pressure. In other words, the higher the vapor pressure of a substance, the lower its normal boiling point will be.
A substance will exist as a gas at ambient temperature and pressure?
A substance will exist as a gas at ambient temperature and pressure if its boiling point is below the ambient temperature and its vapor pressure exceeds the atmospheric pressure at that temperature.
Is vapour pressure intensive property?
Yes, vapor pressure is an intensive property because it does not depend on the amount of substance present. It is characteristic of the specific substance at a given temperature and does not change with the quantity of the substance.
The phase change in which a substance change from a solid to a gas or vapor without changing to a liquid first is?
Sublimation is the phase change in which a substance changes from a solid directly to a gas or vapor without passing through the liquid phase. This process occurs when the substance's vapor pressure exceeds that of its solid form at a particular temperature.
How can one determine the boiling point from vapor pressure?
To determine the boiling point from vapor pressure, one can use the Clausius-Clapeyron equation, which relates the vapor pressure of a substance to its temperature. By plotting the natural logarithm of the vapor pressure against the reciprocal of the temperature, the boiling point can be determined as the temperature at which the vapor pressure equals the atmospheric pressure.
Temperature a substance will change from liquid to gas?
The temperature at which a substance changes from liquid to gas is known as its boiling point. At this point, the vapor pressure of the liquid equals the atmospheric pressure, allowing it to overcome intermolecular forces and transition to a gaseous state.
How can one determine the normal boiling point by using the vapor pressure and temperature?
To determine the normal boiling point using vapor pressure and temperature, one can plot a graph of vapor pressure versus temperature and identify the temperature at which the vapor pressure equals the standard atmospheric pressure of 1 atm. This temperature corresponds to the normal boiling point of the substance.
