What is the effect of decreased pressure on the boiling and freezing point?
Rheed13
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.

∙ 8y agoWater, for example, boils when the vapour pressure of steam is at atmospheric pressure. As you heat water the vapour pressure rises. If the outside pressure was low (top of a mountain) then that vapour pressure would be reached at a lower temperature.
The boiling point will decrease, because boiling is the ability for water to overcome pressure. Less pressure less work needed, thus you will reach the boiling point faster. When air pressure is reduced, the boiling point of water is also reduced. Water boils more easily if it is under less pressure. Conversely, the boiling point rises if water is under increased pressure, which is the principle upon which the pressure cooker is based.

What is the effect of decreased pressure on boiling point and freezing point of water?
water can be compressed and it would make the freezing point and the boiling point lower
What is the effect of salt in boiling and freezing temperatures?
The freezing point is lower and the boiling point is higher.
What temperature does water melt?
== == Pressure has an effect on the freezing point of water, though it isn't as substantial as the effect of pressure on boiling point. We could say that these values are at standard pressure, but realistically there is no noticeable difference of water's freezing point on various altitudes on earth. But it should be noted that if there are ions dissolved in the water, the freezing point will drop significantly due to the added solute. The melting point of water is the same as the freezing point of water; 32 degrees Fahrenheit or 0 degrees Celsius.
How can the boiling point of water be raised or lowered?
because the boiling and freezing points can be from two different substances so one could be frozen at 0 degrees and the other boiling
What is the effect of the salt by usingthe concept of melting point?
Salt water has a lower freezing point and a higher boiling point.
What is the effect of decreased pressure on boiling point and freezing point of water?
water can be compressed and it would make the freezing point and the boiling point lower
What is the overall effect adding a solute to a solution?
boiling point is increased and freezing point is decreased
When is the freezing point of a liquid?
effect of pressure and impurties on the freezing and boiling point of liquids
What is the effect of salt in boiling and freezing temperatures?
The freezing point is lower and the boiling point is higher.
How does the effect of freezing differ from the effect of boiling the enzyme?
Freezing doesn't effect the enzymes since freezing does not permanently affect enzyme structure. Boiling permanently changes the structure and can change the enzymes.
What is the effect of pressure on boiling?
Lowering the pressure the boiling point is also lower.
How are boiling and freezing points of a sample of water affected when salt is dissolved in the water?
the freezing and boiling points rise significantly- this is why when you boil water in a saucepan, like for pasta, it is advised that you put salt in the water so that the water boils at a higher temperature, thus allowing you to heat the water to a higher temperature. hope this helps

What should be the freezing point of water if its boiling point is greater than a 100 degrees?
Water boils at a temperature greater than 100 oC if the pressure is higher than atmospheric pressure but this has no effect on melting point.
What physical effect can change the boiling of substance?
Pressure
What effects do solutes have on a solvent's freezing and boiling boints?
The effect of a solute on the freezing point and boiling point of a solvent is related to what is known as the colligative property. Upon addition of the solute, the freezing point will be lowered, and the boiling point will be increased. The magnitude of the change will depend on the solute and how many particles it forms upon dissolving, and on the nature of the solvent and the freezing/boiling point constant for that solvent.
Does the freezing point of water change with atmospheric pressure as does the boiling point?
No. At higher pressures the water freezes at lower temperatures i.e. lower than zero Celsius. However, note that this is a very subtle effect; it's nowhere near the same order of magnitude as the change in boiling point with pressure. For ordinary atmospheric pressures, the change will be minute, far less than a degree. To give you some idea: at normal atmospheric pressure, about 101,000 Pa, water freezes at 273.15 K. The triple point of water occurs at a pressure of around 600 Pa ... less than 1/100th as much ... and the freezing point only goes up by 0.01 K. It may also be worth noting that water is somewhat unusual in this regard; most substances freeze at HIGHER temperatures at higher pressures.
