Why does adding glycerol and water lead to an increase in temperature?
Wiki User
∙ 9y ago
The reaction of glycerol and water leads to the glycerol competing with the hydrogen bonds of water molecules. This disrupts the formation of ice crystals, depressing the freezing point of water.

What effect does adding a solute have on the boiling point of a solution?
Adding a solute to a solution, or some liquid, causes the boiling point to increase. Think about water, sometimes people throw salt in their water when they're boiling noodles. This causes the boiling point to increase so the water is actually at a higher temperature (although most of the time the amount of salt added isn't nearly enough to cause any measurable change).
Which factors affect water potential in living cells?
Some factors which influence water potential include gravity, pressure, and solute concentration. Adding solute lowers the water potential. An increase of pressure will increase the water potential.
Can ordinary water be boiled in 95 degree Celsius or 105 degree Celsius?
pure water (with no impurities added ) can only boil at 100 degrees Celsius , no other temperature . But if we add impurities to it than the temperature at which the water will boil can increase or decrease. Another point is that when we increase or decrease the atmospheric pressure, the temperature at which ordinary water boils (i.e.100 degrees Celsius) can also increase or decrease.
Does a substances temperature change when it is changing state?
No. During a phase change, a substance will remain at a constant temperature until the change is complete. In the case of melting ice, the heat initially goes into separating water molecules from the ice lattice, which is melting. During that time, the heat goes into continued melting of the ice and the temperature remains constant. Once all of the ice is melted, adding additional heat will increase the temperature of the now liquid water.
What is the amount of table sugar that will dissolve in 1 kg of water can be increased by?
You can increase the temperature of the water.
Does adding chemicals to water increase temperature?
It depends what
Why does temperature of water lowers on adding glucose?
It will increase the surface tension of water hence temperature decreases. If you add phenol to water temperature increase as it decreases the surface tension.
What would increase the salinity of sea water?
Decreasing the temperature, evaporating water, or adding more salt.
An increase in a body of water's temperature caused by adding warmer water is called?
Thermal Pollution.
The temperature of true water is in a beaker is 25 c after adding a piece of magnesium to the water the temperature increase is this an exothermic or an endo thermetic?
exothermic ? because energy released
What is superhydration?

Show by calculation how would you prepare 200ml of 80 percent glycerol?
Take a 500ml beaker, add 160ml of glycerol. make up the volume to 200ml by adding water. Stir them with a magnetic stirrer for a while and here is your 80% Glycerol.
Steps to see if adding salt to water change the temperature at which it boils?
To test if adding salt to water increases the boiling point of the water, do the following: boil a sample of pure water until it boils. Measure the temperature at which the pure water boils. Take another sample of pure water and add salt to it, then boil this sample under the same conditions. Measure the temperature at which the salt water boils. If the latter temperature is higher, salt does increase the boiling point of water.
How do you neutralize Boric Acid in water?
By adding polyhydroxy comp. as Glycerol, Mannitol , H3BO3 acts as strong acid and we can titrate it.
Does the volume of water affect the temperature increase when reacted with calcium oxide?
yeah the temperature does increase, when you increase the volume of water the temperature of calcium hydroxide increases too!
Which process in the water cycle is caused by an increase in temperature?
Evaporation is the process in the water cycle caused by an increase in temperature.
How do you increase your pH?
By adding potash or bicab to the water.
