Which will have the higher vapor pressure at a given temperature: NH3 or PH3? Explain. If liquid A boils at a lower temperature than liquid B then: a) Liquid A has stronger intermolecular forces. b) Liquid A has a lower vapor pressure than...
It's inside these hidden coils that liquid coolant comes to a boil. What makes the coolant boil? The secret is in the relationship between pressure and boiling point. When pressure changes, so does the temperature at which a substance comes to a boil. ...
boiling point,temperature at which a substance changes its state from liquid to gas. A stricter definition of boiling point is the temperature at which the liquid and vapor (gas) phases of a substance can exist in equilibrium. When heat is applied to a liquid, the temperature of the liquid...
freezing point, melting point - the temperature below which a liquid turns into a solid boiling point - the temperature at which a liquid boils at sea level; "they brought the water to a boil" mercury - temperature measured by a mercury thermometer; "the mercury was falling rapidly" room ...

The normal boiling point of an element or a substance is the temperature at which the vapor pressure and the atmosphere are equal, when the atmospheric pressure is defined as 1 atmosphere, True False True or false? Vapor pressure is dependent on temperature. ...

The Clausius–Clapeyron equation describes the relationship between the vapor pressure of a substance, p, and the temperature at which it boils, T: Here ΔH stands for the enthalpy (heat) of vaporization, L is a substance-specific constant, and R is the universal gas constant, 8.314 J/(mol...
"boil" can also describe the effect of extreme heat or temperature on something other than liquids. For instance, "The sun boiled the asphalt" depicts the intense heat of the sun causing the asphalt to soften and become pliable. This usage extends the concept of "boil" beyond...
Thenormal boiling pointis the temperature at which the liquid boils when the external pressure is oneatmosphere(760 torr = 760 mm Hg = 1 atm = 101.3 kPa = 14.7 psi). Pure substances have a discrete boiling point.Mixturesconsisting of two or morechemicalscan have a single boiling point, but...
