As atmospheric pressure increase so does the boiling pont, when atmos. pressure decreases so does boiling point.
A liquid boils when its vapor pressure equals atmospheric pressure.

∙ 11y agoThe boiling point is the temperature at which, at constant pressure, a liquid become a gas.
The vapor pressure is the pressure of vapors above a liquid (or solid), in thermodynamic equilibrium, in a closed systems, at a given temperature.

∙ 12y agoBoiling point of a liquid depends on the external pressure. Higher the pressure higher the boiling point.
Boiling takes place only when the satruated vapour pressure becomes equal to the external pressure.

∙ 13y agoThe boiling point of a substance is the temperature at which the vapor pressure is equal to the pressure of the surrounding atmosphere.
At high altitudes the atmospheric pressure is lower so the boiling point of substances is reduced. A lower temperature is required for the vapor pressure to equal the atmospheric pressure.
The converse is true for increased atmospheric pressure.

∙ 11y agoVapor pressure is the pressure of vapor in equilibrium with the corresponding liquid phase, that is the pressure needed so that the mass per unit time of liquid that goes into vapor balances that of vapor that goes into liquid. When the external pressure is equal to the vapor pressure then the boiling point is reached (this is because vapor bubbles can resist the external pressure and escape the liquid surface),

Why must the boiling point be measured at constant atmospheric pressure?
because otherwise the measurement will be different. This is because the boiling point of thingss is changes at a low atmospheric pressure.
Why does water boil at a lower temperature on a mountain than sea level?
The boiling of any liquid is tied in to the atmospheric pressure, in an open system. Every liquid has it's own vapor pressure, that is the balance between the vapor and liquid phase. When atmospheric pressure decreases, the vapor pressure increases since now there is greater space for the molecules of the liquid to come into vapor phase. At higher altitudes, the atmospheric pressure is lesser, that is, the air is thinner. Thus the liquid can attain higher vapor pressure faster and boil at a lower temperature.
Give two differences between evaporation and boiling?
Evaporation takes place at all temperatures but boiling at one particular temperature When saturated vapour pressure becomes equal to the atmospheric pressure boiling takes place but evaporation is not so
What is the point at which a liquids vapor pressure equals the atmospheric pressure?
This temperature is called the boiling point, and indicates the temperature at which a liquid will assume a gaseous state, given the addition of the heat of vaporization.That is the boiling point.
Is it true that the boiling point of a liquid remains constant at all altitudes?
No. Atmospheric pressure falls the higher you go. The boiling point of a liquid varies with ambient pressure. If the pressure is lower then the boiling point will be lower.
What is the relationship between pressure and the boiling points of liquid?
As atmospheric pressure increase so does the boiling pont, when atmos. pressure decreases so does boiling point. A liquid boils when its vapor pressure equals atmospheric pressure.
What is the relationship of boiling point with atmospheric pressure?
The normal boiling point (also called the atmospheric boiling point or the atmospheric pressure boiling point) of a liquid is the special case in which the vapor pressure of the liquid equals the defined atmospheric pressure at sea level, atmosphere
What is the difference between boiling water and decomposing water?
when vapour pressure>/ = atmospheric pressure then called boiling. sepration of water in hydrogen and oxygen is called decomposition.
How does the boiling point different from lowland and highland?
in lowland the atmospheric pressure is higher so the boiling point will be higher,in highland atmospheric pressure is low so the boiling will be low
Defined as the point as which liquids vapor pressure equals the atmospheric pressure?
The normal boiling point(also called the atmospheric boiling point or the atmospheric pressure boiling point)is the temperature at which the vapor pressure of a liquid equals the atmospheric pressure at sea level, 1 atmosphere.The normal boiling point of water is about 100 degrees Celsius at a pressure of 1 ATM (i.e., 101.325 kPa).General Useful Information:The boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the environmental pressure, but the environmental pressure may or may not be equal to the atmospheric pressure at sea level, 1 ATM.If the surrounding environmental pressure is less than atmospheric pressure, then the boiling point is less than the normal boiling point.If the surrounding environmental pressure is greater than atmospheric pressure, then the boiling point is greater than the normal boiling point.At the boiling point, adding enough heat to the liquid will cause the liquid to vaporize (that is boil or form a gas).
As external pressure such as atmospheric pressure on liquid increases its boiling temperature?
At high pressure the boiling point is higher.
Do all the liquids at their boiling points have same vapour pressure?
At the same atmospheric pressure, yes. That's kind of the definition of boiling point: when the vapor pressure is the same as the atmospheric pressure.
What is the condition which occurs when the atmospheric pressure is equal to the vapour pressure?
boiling
What is the boiling point of ammonium?
The boiling point of ammonia at atmospheric pressure is -33.34oC.
Why must the boiling point be measured at constant atmospheric pressure?
because otherwise the measurement will be different. This is because the boiling point of thingss is changes at a low atmospheric pressure.
What is the relation between pressure and the boiling point of liquid?
The lower the atmospheric pressure, the lower the boiling point of the liquid. For example, at sea level, water boils right at 100 degrees Celsius, but at a high elevation where the atmospheric pressure is lower, the water will boil at below 100 degrees Celsius. This is why some recipes have high-altitude directions, allowing for this property.The higher the air pressure, the higher the temperature of the boiling point.The lower the air pressure is, the lower the temperature of the boiling point.In fact, in very high places like Mt Everest, the boiling point of water is so low that it is difficult or impossible to cook food.
How is evaporation different from boiling?
as the evaporation occurs under the atmospheric pressure that is492degr and the boiling point occurs above the atmospheric pressure different liquids have different boiling points just the boiling point of water is 100deg c
