in short, Atoms must vibrate to break their bonds I.E. from solid state, to liquid state to gas state. with a HIGH pressure the atoms must vibrate faster to become hotter to over come the pressure surrounding it. as pressure decreases, less energy is needed to break the bonds and over come the surrounding pressure, and with that a LOWER amount of energy is needed in LOWER pressure.
HOPE THIS HELPS ;-)
What else can I help you with?
What happends to the boiling point of a substance when pressure above it decreases?
When the pressure above a substance decreases, the boiling point of the substance will also decrease. This is because lower pressure means that less energy is required for the substance to overcome the atmospheric pressure and transition from liquid to gas phase.
Is it true that boiling point remain constant in all altitudes?
No, the boiling point decrease at high altitudes.
How does pressure affect boiling point?
An increase in pressure raises the boiling point of a liquid because it takes more energy for the liquid molecules to escape the higher atmospheric pressure above them. Conversely, decreasing the pressure lowers the boiling point as it requires less energy for the molecules to overcome the reduced atmospheric pressure.
What effect would a decrease or increase in barometric pressure have on the boiling point?
If you were to travel to Denver, the mile high city, air pressure is reduced. This makes it easier for gas molecules to escape the liquid, hence the boiling point lowers. On the other hand, when pressure increases, gases have a harder time escaping the liquid so the boiling point must increase.
Does the boiling point increase with pressure?
Yes, the boiling point of a substance increases with an increase in pressure.

Why the boiling point of water is 98 in Kaghan?
The boiling point of water decrease when the altitude increase and the atmospheric pressure decrease.
What is the term for the Boiling of a liquid caused by decrease in pressure rather than by an increase in temperature?
This is known as "boiling point elevation." It occurs when the boiling point of a liquid increases due to a decrease in pressure, such as at higher altitudes.
Is it true that boiling point remain constant in all altitudes?
No, the boiling point decrease at high altitudes.
Do the boiling point of water directly proportional to pressure?
Yes, the boiling point of water is directly proportional to pressure. As pressure increases, the boiling point of water also increases. This is because higher pressure prevents the liquid molecules from escaping into a gaseous state, requiring higher temperatures to overcome the pressure and boil.
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.
As you go to higher elevations above sea level the boiling point of water?
as you go higher above sea level, pressure decreases. Due to the decrease in pressure, the temperature needed for water to boil is less than it is than it would be at sea level. Thus, it would take less heat energy for the bonds to break and become a gas than it would in an environment with more pressure.
How does pressure affect boiling point?
An increase in pressure raises the boiling point of a liquid because it takes more energy for the liquid molecules to escape the higher atmospheric pressure above them. Conversely, decreasing the pressure lowers the boiling point as it requires less energy for the molecules to overcome the reduced atmospheric pressure.
When a liquid sample is taken from sea level to a higher elevation what happens to the external pressure on the liquid and the boiling point of the liquid?
atmospheric pressure is lower and the boiling point is less
What are the properties of a colligative property?
1. Vapor pressure lowering: the decrease in vapor pressure with increasing the number of solute molecules in solution. 2. Boiling point elevation: the increase in boiling point with increasing number of solute molecules in solution. 3. Freezing point depression: the decrease in freezing point with increasing number of solute molecules in solution. 4. Osmotic pressure
What effect would a decrease or increase in barometric pressure have on the boiling point?

Why doeswater's boiling point decrease with increase in elevation?
Water's boiling point decreases with an increase in elevation because the atmospheric pressure decreases at higher elevations. Water boils when its vapor pressure equals the atmospheric pressure. As atmospheric pressure decreases with elevation, the vapor pressure required to boil water also decreases, resulting in a lower boiling point.
