What are the considerations must be made when examining the boiling point?
When examining the boiling point, consider the type of substance (e.g. organic, inorganic), intermolecular forces present, atmospheric pressure, and purity of the substance. These factors can affect the boiling point of a substance.
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.
Is boiling point of water extensive or intensive property?
Boiling point of water is an intensive property because it does not depend on the amount of the substance present. Water will always boil at 100 degrees Celsius at standard atmospheric pressure regardless of how much water is being heated.
Is Pressure an extensive or intensive property?
Pressure is an intensive property because it does not depend on the amount of substance present. It is a state function, meaning it does not change with the quantity of the substance being measured.
The boiling point of a substance is affected by what?
the mass of the substance Well, the mass of the molecules of the substance. The amount of materail does not affect the boiling point. However, the forces between the molecules does affect how much energy is needed to change the liquid to vapor. Heavier molecules have higher forces. Polar molecules have higher forces, but not as high as charged ions. Also, the atmospheric pressure on the liquid affects the boiling point. Higher pressure helps keep the liquid in the liquid state. Lower pressure makes it easier for the vapor to break out. Water boils at a lower temperature in the mountains than it does on the sea shore. That's why there are special directions for baking cakes at high altitude.
What substance present in your body balances the atmospheric pressure actin on us?
what substance present in your body balances the atmospheric pressure action on us
What is the total pressure gauge pressure plus atmospheric pressure?
Total pressure is equal to the sum of gauge pressure and atmospheric pressure. Atmospheric pressure is always present and contributes to the total pressure measurement.
What is difference between extensive and intensive properties?
* Intensive - Properties that do not depend on the amount of the matter present. ** Color ** Odor ** Luster - How shiny a substance is. ** Malleability - The ability of a substance to be beaten into thin sheets. ** Ductility - The ability of a substance to be drawn into thin wires. ** Conductivity - The ability of a substance to allow the flow of energy or electricity. ** Hardness - How easily a substance can be scratched. ** Melting/Freezing Point - The temperature at which the solid and liquid phases of a substance are in equilibrium at atmospheric pressure. ** Boiling Point- The temperature at which the vapor pressure of a liquid is equal to the pressure on the liquid (generally atmospheric pressure). ** Density - The mass of a substance divided by its volume * Extensive - Properties that do depend on the amount of matter present. ** Mass - A measurement of the amount of matter in a object (grams). ** Weight - A measurement of the gravitational force of attraction of the earth acting on an object. ** Volume - A measurement of the amount of space a substance occupies. ** Length
About What fraction of atmospheric pressure greatest at the surface of earth?
At the surface of the Earth, about 99% of the atmosphere's total mass is located below 32 km. This is where most of the atmospheric pressure is concentrated. Therefore, the greatest fraction of atmospheric pressure is present at the Earth's surface.
What are the considerations must be made when examining the boiling point?
When examining the boiling point, consider the type of substance (e.g. organic, inorganic), intermolecular forces present, atmospheric pressure, and purity of the substance. These factors can affect the boiling point of a substance.
What determines the phase of a substance?
The phase of a substance is determined by its temperature and pressure, as well as the intermolecular forces present within the substance. Changes in temperature and pressure can cause a substance to transition between solid, liquid, and gas phases.
What fraction of atmospheric pressure at sea level is atmospheric at La Paz?
La Paz, Bolivia, is situated at a high altitude of approximately 3,650 meters (about 11,975 feet) above sea level. At this elevation, the atmospheric pressure is significantly lower than at sea level, typically around 60-65% of atmospheric pressure at sea level. Therefore, the fraction of atmospheric pressure at sea level that is present in La Paz is roughly 0.6 to 0.65.
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 does pressure change as the distance from earth increases?
As distance from Earth increases, the atmospheric pressure decreases. This is because there are fewer air molecules present at higher altitudes, leading to lower pressure.
What is a space that has no matter in it?
A vacuum is a space devoid of matter, where the pressure is lower than atmospheric pressure. It is commonly found in outer space, with very few particles present.
What happens to atmospheric pressure as altitude increase?
This would actually be a simple answer: Pressure decreases. Simply because of the fact that as altitude increases, the less air there is on top of you, and the lower the pressure would be.
Where would atmospheric pressure be greatest at sea level on a mountaintop at the altitude at which planes fly or at the outer edge of the atmosphere?
At sea level, atmospheric pressure would be greatest because of the weight of the entire column of air above that point. As you move higher up a mountain, atmospheric pressure decreases due to the lower column of air above. However, at the outer edge of the atmosphere, the pressure drops significantly as there is almost no air present in this region.
