What is the effect of decreased pressure on boiling point and freezing point of water?
Decreased pressure lowers the boiling point of water because it reduces the pressure exerted on the liquid, allowing the water molecules to escape into the vapor phase more easily. However, decreased pressure has a less significant effect on the freezing point of water compared to the boiling point, as freezing point is more influenced by the presence of impurities in the 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.
Frozen salt water melt faster then frozen fresh water?
Salt lowers the melting or freezing point of water. The effect is termed 'freezing point depression'. Therefore frozen salt water melts faster and remain melted for long.
What effect does freezing have on pepsin activity?
Heat affect any enzyme and so pepsin. A temperature about 80 degrees can degarade most of the proteins and pepsin. At this temperature pepsin loose its structure and can not be active after that.
Does solute effect the freezing point of water?
the temperature at which the solution freezes is lowered.
Does freezing water effect the neutrality of water?
no
What is the Effect of salt on water?
it lowers the freezing point of the water
Why does salt effect the freezing point of water?
Salt mixes with the water raising it's freezing temperature above normal.
Why is water activity a better measure of concentration when calculating freezing point depression or boiling point rise?
Water activity takes into account only the available water molecules that contribute to colligative properties, which affects freezing point depression and boiling point elevation more accurately than traditional concentration measurements. It focuses on the water molecules that are free to participate in these colligative properties, providing a more precise measure of the effect on the freezing or boiling point.
How will the mass of the water be affected when the waterfreezes?
There is no effect of freezing on the mass of water when it freezes. The thing which is affected by freezing is its volume and hence, it's density.
What is the effect of pH on the freeziing point of water?
If the water contain impurities the freezing point is lowered.
How does human activity effect the water in the ocean?
Poullation
How does salt effect the properties of water?
Salt increases the boiling point of water and lowers its freezing point.
How does freezing temperature affect mocroorganisms and enzymes?
Freezing temperature make ice of the water in bacteria and completely stop there metabolic activity. Enzymes do not work at freezing temperature as they have no scope for movement in solid ice. So there activity halted.
Which salts make water solid?
Sodium, potassium, calcium chlorides have the effect of lowering the freezing point of water.
Does salt or sugar work better in making water cold?
Salt works better in making water cold because it lowers the freezing point of water, allowing it to reach colder temperatures without freezing. Sugar does not have the same effect as salt on the freezing point of water.
What is the effect of decreased pressure on boiling point and freezing point of water?
Decreased pressure lowers the boiling point of water because it reduces the pressure exerted on the liquid, allowing the water molecules to escape into the vapor phase more easily. However, decreased pressure has a less significant effect on the freezing point of water compared to the boiling point, as freezing point is more influenced by the presence of impurities in the water.
