What decreases with increasing attraction between molecules?
Freezing point raised Boiling point raised etc. As the molecules in the substance is more strongly bonded together and is hard to separate.
What is the relationship between presssure and the boiling point of Liquids?
Boiling point is nothing but point at which liquid starts changing from liquid state to vapor state. liquid changes to vapor when vapor pressure equal to surrounding pressure. so if surrounding pressure is less boiling point is less and boiling point is high if surrounding pressure is high this point is on view of pressure
Does reduced vapor pressure at high altitudes causes a liquid to boil at a higher temperature?
The higher the vapor pressure of a liquid at a given temperature, the lower the normal boiling point (i.e., the boiling point at atmospheric pressure) of the liquid.
What happens to boiling point above sea level?
As you go above sea level, the atmospheric pressure decreases, and so the boiling point also decreases to below 100ºC.
Describe the difference if any there would be between the boiling point of alcohol measured in Houston and in Denver the mile high city?
the boiling point would be lower because pressure decreases as altitude increases. the boiling point would be lower because pressure decreases as altitude increases.
What happends to water's boiling point as pressure is increased?
boiling point increases
What 2 factors affect the boiling point of water?
Pressure & Temperature :) Apex
What would happen to the boiling point of a substance if the elevation were to rise?
Actually, as you rise in elevation in atmoshpere im assuming, the pressure decreases. This pressure drop will cause the boiling point of anything to rise, therefore requiring more energy to boil.
What decreases with increasing attraction between molecules?
Freezing point raised Boiling point raised etc. As the molecules in the substance is more strongly bonded together and is hard to separate.
Why altitude affects boiling point?
Ya ........ if you have an egg on the top of high mountain the altitude and less air density causes lower boiling points and when you get higher it reduces the boiling point of the water and it is due to atmospheric pressure.Boiling is directly proportional to atmospheric pressure which becomes lower when we go above the sea level example mountainous areas.

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 effect of decreased pressure on the boiling and freezing point?
As pressure decreases, the boiling point of water will also decrease. Backpackers camping in the high mountains are familiar with the phenomena when they get water boiling - and find that it is still only lukewarm because the atmospheric pressure at their high altitude is so low.
What physical effect can change the boiling of substance?
Pressure
What is the relationship between presssure and the boiling point of Liquids?
Boiling point is nothing but point at which liquid starts changing from liquid state to vapor state. liquid changes to vapor when vapor pressure equal to surrounding pressure. so if surrounding pressure is less boiling point is less and boiling point is high if surrounding pressure is high this point is on view of pressure
What happens at a substance's boiling point?
Its vapor pressure equals atmospheric pressure.
Is there a relationship between boiling and pressure?
Yes, there is. Higher pressure increases the boiling point and lower pressure decreases it. That is why a pressure cooker works and why water boils at lower temperatures in high altitudes.
What effcet does altitude have on boiling point of water?
Higher altitude decreases the boiling point of water. Boiling point is defined as the point at which the vapour pressure of the substance above the liquid is equal to the external atmospheric pressure. Since the external atmospheric pressure is lower at higher altitudes, a lower vapour pressure of water is required for water to boil and therefore a lower temperature is required to achieve the desired vapour pressure.
