What is the accurate definition of vapor pressure?
Vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature in a closed system. Vapor pressure is also known as equilibrium vapor pressure.
What can be said about boiling point of a liquid?
The stronger the intermolecular forces in a liquid, the higher the boiling point. -APEX
What is the boiling point of a compound?
as far as i know the B.Pt. is defined as " when the vopour pressure of the liquid is equal to the atomospheric pressure then it is said to be the boiling point of the liquid." similarly "when the vapuor pressure of the solid is equal to atmospheric pressure then its corresponding temperature is called melting point of that compound." so a compound may be a low melting one but the same compound may be ahigh boiling liquid. this is due to the inter & intra molecular forces that exists in the molecules. so there is no specific equation that a compound having a m.p. of 102c will have a b.pt. of some particular value.
Why does water boil at 100 degrees centigrade?
It is a natural property of a liquid to boil at a particular temperature--or actually in a temperature range, because low atmospheric pressure can make the boiling point a little lower, or high pressure can make it a little higher. That being said, the Celsius (a.k.a. Centigrade) scale was set up with 100 degrees being the boiling point of water with the atmospheric pressure at sea level, and also with zero degrees at the freezing point. Calling those temperatures 100 and 0 was arbitrary.
What is liquid's boiling point?
Boiling point is the temperature in which a substance in a liquid state turns to a gas state. In a pure substance (an element or 1 compound) that temperature is a unique property. For example, pure water boils at 100 degrees Celsius. Methanol has a boiling point of 64.7 degrees Celsius. In pure substances the temperature time graph makes a plateau. The boiling point is the same as the condensation point (where a gas turns into a liquid) for that substance.

Vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature in a closed system. Vapor pressure is also known as equilibrium vapor pressure.
What can be said of a boiling point of a liquid?
The boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure, causing the liquid to change into a gas. It is a characteristic property of the liquid and can be influenced by factors such as pressure and impurities in the liquid.
Why rainwater evaporates when it is not 100 degrees Celsius?
Water evaporates at almost any temperature. However, at higher temperatures, the vapor pressure is higher. It is said to be boiling when the vapor pressure is equal to the atmospheric pressure.

What causes the high surface tension and low vapor pressure of water?
Hydrogen bonding causes the inward force that minimizes the surface area of water, and the tendency of water molecules escaping this bond to become vapor is slim and/or slow, thus creating it's low pressure.

When a substance passes directly from solid to gaseous state on heating it is said to be?
When a substance passes directly from a solid to a gaseous state upon heating, it is said to undergo sublimation. This process occurs without the substance first becoming liquid, and is commonly observed in materials like dry ice (solid carbon dioxide) and iodine. Sublimation typically occurs under specific temperature and pressure conditions where the solid's vapor pressure exceeds atmospheric pressure.
Air that has reached its water-vapor capacity is said to be what?
Air that has reached its water-vapor capacity is said to be saturated.
My doctor asked me if a patient of ours had diabetes. I said no just high blood pressure. He said that is diabetes. Does having high blood pressure mean you have diabetes?
No. Diabetes is just one of many causes of high blood pressure. Your doctor must have been joking, or at least i hope he was otherwise your patients should be scared.....
Is low pressure or high pressure stronger?
High pressure is stronger. Pressure is caused by the gas particles in a container hitting the sides of said container. At high pressure, the particles hit the sides of the container much more and therefore are pushing harder on the sides.
