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 is the effect of salt in boiling and freezing temperatures?
The freezing point is lower and the boiling point is higher.
How does elevation effect freeze point?
As elevation increases, the atmospheric pressure decreases. This causes the boiling point of water to decrease, but the freezing point remains relatively unaffected. Therefore, elevation does not significantly impact the freezing point of water.
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 does the effect of freezing differ from the effect of boiling in salivary amylase and cellulose?
Freezing would denature salivary amylase by disrupting its molecular structure, rendering it inactive. However, boiling would also denature salivary amylase but much more rapidly and completely. Cellulose is not affected by freezing but boiling can break down its rigid structure, making it more digestible.
What is the overall effect adding a solute to a solution?
boiling point is increased and freezing point is decreased

The freezing point and the boiling point of water can be altered by a variety of techniques Which of the following has little or no effect on the boiling point of water?
Pressure changes have little effect on the boiling point of water. The boiling point of water changes depending on the pressure, but the effect is minimal compared to other factors like adding solutes or using a catalyst.
What is the effect of pressure on boiling?
Lowering the pressure the boiling point is also lower.
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.
When is the freezing point of a liquid?
The freezing point of a liquid is the temperature at which it changes from a liquid to a solid state. This temperature is specific to each substance and can vary depending on the particular properties of the liquid.
How does elevation effect freeze point?
As elevation increases, the atmospheric pressure decreases. This causes the boiling point of water to decrease, but the freezing point remains relatively unaffected. Therefore, elevation does not significantly impact the freezing point of water.
What physical effect can change the boiling of substance?
Pressure

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.
