What is the accurate definition of vapor pressure?
Vapor pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) in a closed system at a given temperature. It represents the tendency of a substance to evaporate or transition into the gas phase.
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?
The boiling point of a compound is the temperature at which the vapor pressure of the liquid equals the external pressure. It refers to the point at which the liquid changes into a gas. Each compound has a specific boiling point unique to its chemical structure and properties.
Why does water boil at 100 degrees centigrade?
Water boils at 100 degrees Celsius because this is the temperature at which its vapor pressure equals the atmospheric pressure. At this point, water molecules have enough thermal energy to overcome the intermolecular forces that hold them together in the liquid phase, allowing them to escape as vapor.
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.

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.

The stronger the intermolecular forces in a liquid, the higher the boiling point. -APEX
When a liquid is thick such as honey it is said to have a high?
high viscocity

What causes the high surface tension and low vapor pressure of water?
The high surface tension of water is due to the strong hydrogen bonding between water molecules, which creates a cohesive force at the surface. The low vapor pressure of water is a result of these same hydrogen bonds, which make it more difficult for water molecules to escape into the vapor phase.
Why does water boil at 100 degrees centigrade?
Water boils at 100 degrees Celsius because this is the temperature at which its vapor pressure equals the atmospheric pressure. At this point, water molecules have enough thermal energy to overcome the intermolecular forces that hold them together in the liquid phase, allowing them to escape as vapor.
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.....
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.
Is low pressure or high pressure stronger?
High pressure is stronger than low pressure. High pressure systems are associated with clear skies and calm weather, while low pressure systems are typically linked to stormy conditions. High pressure occurs when air is sinking, while low pressure occurs when air is rising.
Whats the wind pattern around a high pressure area?
The wind pattern around a high pressure area is clockwise (in the northern hemisphere). It is said to resemble a spinning disk, as opposed to a spinning sphere.
