The boiling point is the temperature at which a substance starts converting from its liquid state to its gas state under standard conditions of temperature and pressure. The boiling point of pure water is 100 degrees Celsius. Answer and Explanation:1 ...
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...
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...
When pressure changes, so does the temperature at which a substance comes to a boil.就是在这组内置盘管里,液态冷却剂会沸腾。是什么使冷却剂沸腾的呢?答案在于压强和沸点之间的关系。当压强发生改变,物质的沸点也会跟着变化。 As the liquid coolant passes through a valve into the hidden coils, the ...
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 temperature that rises or falls. The amount by which no substance expands and contracts for one degree is not usually the same as that for a different substance. Thus, for a given rise in temperature, a piece of brass expands a little more than a piece of copper and much more than...
What is the name of the temperature and pressure conditions at which water can be in the solid, liquid and gas phases simultaneously? What is the air pressure in a place where water boils at 70 C? At what temperature does water boil at the top of Mount Everest?
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...
