What 2 solute molecules mixed with the solvent molecules in a solution cause the freezing point of a solution to be than it is for an equal volume of pure?
lower, solvent, lower, solvent
What does saturateo solution mean in chrmistry?
In chemistry, a saturated solution refers to a solution in which no more solute can dissolve at a given temperature and pressure. This means that the maximum amount of solute has been dissolved in the solvent. Any additional solute added to the solution will remain undissolved and form a precipitate.
WHAT CAUSE mucous cell?
mucous solute
What is the effect of freezing temperatures on rocks?
This process is called weathering. Very cold temperatures cause any water in the cracks of the rocks to freeze and expand which puts pressure on the rocks. The water thaws when the temperature rises. Repeating this process over and over will eventually undermine the strength of the rock causing it to crumble.
Why in cold countries people sprinkle salt on snow?
Salt lowers the melting/freezing temperature of water, thus causing ice and snow to melt. However in places where it is VERY COLD the salt cannot lower the melting/freezing temperature enough to cause it to melt, so sand is used instead as it improves traction, even with the ice and snow still there.
What will adding solute to pure solvents cause?
Adding a solute to a pure solvent will lower the freezing point, elevate the boiling point, and lower the vapor pressure.
Does freezing a chicken egg hurt it?
yes freezing a chicken egg will cause it to swell and crack.
Can an avalanche cause another natural disaster?
Yes the snow can melt and cause a flood if the temperature is above freezing point and if it is not removed quickly.
What can helium do to the body?
Helium, is not oxygen, and as such a large presences of helium in the body can asphyxiate and cause death.

Does temperature bellow freezing point cause rock to break?
Rocks are already frozen (unless it is molten lava). Otherwise mountains would simply be piles of dust. Water freezing in cracks or variations in the rock can cause breaking.
What is the most common cause of hypothermia?
Getting wet
Freezing point depression of a solvent resulting from the introduction of a solute?
Yes...With the introduction of a solute, a solvent's freezing point will go down. The most simple example is during the winter. When people are putting salt on the roads and sidewalks, what that does is lower the ice's freezing point, meaning it will have to be colder before the ice freezes. So, if it's 31 degrees outside, that's cold enough for ice to form, but if you put salt down, the salt will mix with the water trying to freeze and lower it's freezing point to, let's just choose a number, 26 degrees. Since it is not 26 degrees out, the ice will not be able to form. Then the freezing rate is zero, and the melting rate does not change, so eventually all the ice will melt because a solute was introduced to cause freezing point depression.

This means that the maximum amount of solute has been dissolved in the solvent. Any additional solute added to the solution will remain undissolved and form a precipitate.
Can freezing cause a density current?
No, trade winds and evaporation can cause a density current but not freezing.
WHAT CAUSE mucous cell?
mucous solute
Will freezing a germ kill it?
the answer is yes. this is because the decreasing temperature would cause most of the bacteria cells to die and eventually the bacteria would die.
