Why is vapor pressure reduced in a solution with a nonvolatile solute?
Yes, nonvolatile solute lowers the vapor pressure and increases the boiling point. For instance, salt is an example of an nonvolatile solute in water. Ever wonder why salt is used in icy roadways in the winter? Because salt help inhibit the crystallization of water particles into ice by lowering the freezing point.
Explain what hppens to air pressure as you move away from the earths surface?
Pressure increases as you get closer to earth.
If the pressure of a gas in a container is 10psi what will the pressure be in the volume of the container is reduced to one-half of its original size?
If the volume of the container is reduced to one-half of its original size, the pressure will increase proportionally according to Boyle's Law. So if the original pressure was 10 psi, then the new pressure would be 20 psi when the volume is reduced by half.
What is a vacuum distillation?
When pressure is reduced the boiling point will also reduce
What happen to the pressure of a gas if the volume of the gas is tripled of a constant temperature?
The pressure is reduced to one third of the original pressure. The pressure will stay the same you are only changing the volume

How do sodas get their bubbles?
Because sodas are a solution of CO2 in water and flavorings. The beverage does not bubble while the container is closed because the pressure is high. When the container is opened the pressure is reduced so the solution becomes oversaturated and starts releasing gas so the solution bubbles.
The solute molecules mixed with the solvent molecules in a solution cause the of a solution to be higher than it is for an equal volume of pure solvent?
Raoult's Law and Vapor Pressure LoweringWhen a nonvolatile solute is added to a liquid to form a solution, the vapor pressure above that solution decreases. To understand why that might occur, let's analyze the vaporization process of the pure solvent then do the same for a solution. Liquid molecules at the surface of a liquid can escape to the gas phase when they have a sufficient amount of energy to break free of the liquid's intermolecular forces. That vaporization process is reversible. Gaseous molecules coming into contact with the surface of a liquid can be trapped by intermolecular forces in the liquid. Eventually the rate of escape will equal the rate of capture to establish a constant, equilibrium vapor pressure above the pure liquid.If we add a nonvolatile solute to that liquid, the amount of surface area available for the escaping solvent molecules is reduced because some of that area is occupied by solute particles. Therefore, the solvent molecules will have a lower probability to escape the solution than the pure solvent. That fact is reflected in the lower vapor pressure for a solution relative to the pure solvent. That statement is only true if the solvent is nonvolatile. If the solute has its own vapor pressure, then the vapor pressure of the solution may be greater than the vapor pressure of the solvent.Note that we did not need to identify the nature of the solvent or the solute (except for its lack of volatility) to derive that the vapor pressure should be lower for a solution relative to the pure solvent. That is what makes vapor pressure lowering a colligative property--it only depends on the number of dissolved solute particles.summarizes our discussion so far. On the surface of the pure solvent (shown on the left) there are more solvent molecules at the surface than in the right-hand solution flask. Therefore, it is more likely that solvent molecules escape into the gas phase on the left than on the right. Therefore, the solution should have a lower vapor pressure than the pure solvent.Figure %: The Vapor Pressure of a Solution is Lower than that of the Pure Solvent
Is increase of vapor pressure a colligative property?
Yes, an increase in vapor pressure is a colligative property. Colligative properties depend on the number of solute particles in a solution, not their identity. Therefore, increasing the concentration of a solute in a solution will result in an increase in vapor pressure due to reduced effective solute-solvent interactions.
Why do bubbles vanish to air slightly as the carbonated drink is exposed to air longer?
Because sodas are a solution of CO2 in water and flavorings. The beverage does not bubble while the container is closed because the pressure is high. When the container is opened the pressure is reduced so the solution becomes oversaturated and starts releasing gas so the solution bubbles.
what happens to a gas as pressure is reduced?
As pressure is reduced, the volume of the gas will increase. This is described by Boyle's Law, which states that pressure and volume are inversely proportional. Therefore, as pressure decreases, the gas molecules have more space to move around, causing the gas to expand.
What is reduced pressure steam?
Steam that was reduced in pressure from that at which it was generated in the boiler. Reducing the steam pressure can be accomplished by running it through a turbine or engine, a reducing valve or a regulator. Reduced pressure steam is often used for auxiliary equipment or heating systems after the primary process has been supplied steam at the generated pressure.
Explain what hppens to air pressure as you move away from the earths surface?
Pressure increases as you get closer to earth.
Why Glycerin is distilled at reduced pressure?
glycerin is distilled at reduced pressure because it has boiling point of 290 degree celsius under atmospheric pressure it slightly decomposes but under reduced pressure it distills unchanged
What happens to gas when pressure is applied to it?
the pressure and the temperature increases, and the volume is reduced.
What is a sentence for hypotonic?
Hypotonic means having reduced pressure or tone. That solution is hypotonic compared to this one.
If the pressure of a gas in a container is 10psi what will the pressure be in the volume of the container is reduced to one-half of its original size?
If the volume of the container is reduced to one-half of its original size, the pressure will increase proportionally according to Boyle's Law. So if the original pressure was 10 psi, then the new pressure would be 20 psi when the volume is reduced by half.
