How does adding a solute affect the vapor pressure?
Adding a solute in a liquid the vapor pressure is lowered.
If you changed the water to water vapor in a pressure cooker what volume would the water vapor occupy?
If it remains sealed the volume remains the same.
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.
Is increase of vapor pressure a colligative property?
The lowering of the vapor pressure is a colligative property.
Which of the colligative properties is not dependent on vapor pressure boiling point elevation vapor pressure reduction osmotic pressure?
Osmotic pressure.
What are some elements that change air pressure?
temperature (heat), volume, water vapor, and altitude (how high or low it is) all affect air pressure
How does the density of water affect its boiling point?
The boiling point (of any compound) is ONLY affected by (vapor) pressure. Density of a gas (vapor) is another property that -in another way- may be affected by pressure.
How does adding a solute affect the vapor pressure?
Adding a solute in a liquid the vapor pressure is lowered.
If you changed the water to water vapor in a pressure cooker what volume would the water vapor occupy?
If it remains sealed the volume remains the same.
Why is dry volume different from wet volume?
Wet volume includes the vapor pressure of water, while dry volume does not.
What factors affect the rate of evaporation?
Temperature, Pressure, Humidity (vapor pressure)
What are the factors affect air pressure?
Three factors that affect air pressure are temperature, altitude, and water vapor.
5 If you changed liquid water to water vapor in a pressure cooker what volume would the water vapor occupy?
The answer would depend on the pressure attained by the cooker.
What are factors that affect gas pressure?
There are two factors that affect gas pressure. These factors are temperature and volume. Higher volume means lower pressure. Higher temperature means higher pressure.
How does temperature affect vapor pressure?
Vapor pressure increases with temperature. As the temperature increases ,molecules of liquid find it easier to escape.
What are factors affecting the reid vapor pressure of an oil?
The amount of light components in the oil affect the reid vapor vapor pressure. In petroleum products such as gasoline, the amount of butane in the gasoline blend has a strong affect on the Reid Vapor Pressure. To reduce RVP more stripping steam can be added to the product strippers. The fractionation in the debutanizer might also need to be adjusted to affect the RVP.
What effect does pressure have on water?
Water is effectively an incompressible substance, so pressure does not affect its' volume. However, its boiling and freezing points are directly related to the external pressure. Water boils when its vapor pressure is equal to the external pressure (or the atmospheric pressure if it is contained in some uncovered pot). Greater external pressure requires higher temperature for water so as to have that value of vapor pressure for it to boil. This is how pressure affects water.
