The vapor pressure of water is the pressure of the water vapor present in the air. The lower the vapor pressure, the less water vapor is present in the air. The higher the vapor pressure, the more water vapor is present in the air.

The atmospheric pressure and temperature also affect the amount of water vapor present in the air. At sea level, where the atmospheric pressure is highest, the air can hold more water vapor than at higher altitudes, where the atmospheric pressure is lower.

The vapor pressure of water is determined by its temperature. The higher the temperature, the higher the vapor pressure. So, which sample of water has the lowest vapor pressure?

The answer is the sample of water with the lowest temperature.

Based on Reference Table H, Which Sample Has the Highest Vapor Pressure

If you’re looking at the vapor pressures of different samples, the one with the highest vapor pressure is going to be the most volatile. In other words, it will have the highest tendency to change from a liquid to a gas at any given temperature. This makes it important to take care when handling and storing this type of sample.

A Liquid Has a Vapor Pressure of 90 Kpa at 75

C What is vapor pressure? Vapor pressure is the pressure of a vapor in equilibrium with its non-vapor phases.

For example, water has a vapor pressure of 23.76 kPa at 25 degrees Celsius. This means that if you have a container of water at this temperature, the partial pressure of the water vapor in the air above the water will be 23.76 kPa. The higher the temperature, the higher the vapor pressure.

The vapor pressure of a liquid is also dependent on the type of liquid. For example, mercury has a much higher vapor pressure than water (1733 kPa at 20 degrees Celsius compared to 23.76 kPa). This is because mercury molecules are much smaller than water molecules and can thus escape from the surface of the liquid more easily.

So what does it mean when we say that a liquid has a vapor pressure of 90 kpa at 75 degrees Celsius? It means that if we have a container of this liquid at this temperature, the partial pressure of the vapors in equilibrium with the liquid will be 90 kPa. This is relatively high for most liquids; however, there are some liquids (like mercury) whose vapors exert far greater pressures even at lower temperatures.

How to Determine Highest Vapor Pressure

When it comes to determining the highest vapor pressure, there are a few different things that you will need to take into account. The first is the temperature of the liquid in question. The higher the temperature, the higher the vapor pressure will be.

You will also need to consider the atmospheric pressure and how much liquid is present. With all of these factors taken into account, you should be able to determine the highest vapor pressure for a given situation.

What is the Normal Boiling Point for Substance X

The normal boiling point for substance X is the temperature at which it changes from a liquid to a gas. The boiling point of a substance depends on its pressure. For example, water boils at 100 degrees Celsius (212 degrees Fahrenheit) at sea level, but only at 93 degrees Celsius (199.4 degrees Fahrenheit) at an altitude of 1,000 meters (3,281 feet).

One Similarity between All Mixtures And Compounds is That Both

Both mixtures and compounds are made up of two or more elements. The key difference between a mixture and a compound is that a compound is held together by chemical bonds, while a mixture is not. This means that the properties of a compound are different from those of its individual elements, while the properties of a mixture are simply the sum of its parts.

One similarity between all mixtures and compounds is that both are composed of two or more elements. The key difference between these two types of matter is that compounds are held together by chemical bonds, while mixtures are not.

What Has the Lowest Vapor Pressure?

If you’re looking for a substance with a low vapor pressure, you might want to consider mercury. Mercury has one of the lowest vapor pressures of any element at room temperature. This is due to the fact that mercury is a heavy metal with a relatively high boiling point.

Does Water Have the Lowest Vapor Pressure?

No, water does not have the lowest vapor pressure. In fact, it has one of the highest vapor pressures of any substance. This is because water molecules are highly attracted to each other and require a lot of energy to break apart.

When water is heated, the molecules move faster and have enough energy to overcome this attraction and escape into the air as vapor.

Which of the Following in Water Possesses the Lowest Vapour Pressure?

The lowest vapour pressure in water is possessed by ice. When water freezes, the molecules arrange themselves into a crystalline structure that is more dense than liquid water. This means that there are fewer molecules per unit of volume available to escape into the gas phase, and so the vapour pressure is lower.

Why is the Vapor Pressure of Water Low?

The vapor pressure of water is low because the molecules of water are attracted to each other by hydrogen bonds. When water molecules are in the liquid state, they are constantly forming and breaking hydrogen bonds with each other. In order for a molecule of water to escape from the surface of the liquid and enter the gas phase, it must first break away from all of the other molecules it is hydrogen-bonded to.

This requires a lot of energy, which raises the boiling point of water.

Conclusion

If you’re looking for the sample of water with the lowest vapor pressure, look no further than ice water. That’s because the molecules in a solid are more tightly packed together than those in a liquid, which means that there are fewer molecules available to escape into the gas phase.
