in polar substances, such as water, ionic impurities usually decrease the freezing point, requiring a lower temperature since bonds between molecules (intermolecular bonding) are disrupted more and more at higher salt concentrations. Organic substances also expereinece a decreaesed melting point when impure, due to one substance dissolving the other and vice versa. In general, freezing points are decreased by impurities if the impurities are miscible in the substance.

What is the freezing point of a wrench?
A wrench has no freezing point, and anyway your hands will freeze long before any wrench is even affected.
What does ethylene do to the solution in a vehicles radiator?
Ethylene glycol mixed up to 50% with water, lowers the freezing point of the mixture, while remaining an excellent heat transfer medium. It protects the engine from either freezing or from overheating.
What is the melting point of petrol and diesel?
These data depends strongly on the chemical composition. For gasoline: the freezing point is from -40 0C to -60 0C For Diesel fuel: the freezing point is from -6 0C to -20 0C
What is the melting point of Celsius?
Celsius is a measure of temperature not a substance, and therefore it has no melting point. What is the melting point of what material in Celsius? [You haven't named the substance you want the melting point of/for]
What is the Freezing point of fish oil?
Lower than -18 c as I have tried.
What occurs at the freezing point of a substance?
At the freezing point a substance become a solid.
What are the effect of impurities on the freezing point of water?
Impurities in water lower its freezing point and raise its boiling point. This occurs because impurities disrupt the formation of ice crystals, requiring a lower temperature to overcome these disruptions and freeze the water.
Is the melting point the same temperature as the freezing point for a substance?
freezing ur mamas as
What happens to the melting and boiling point of a substance if it contains impurity?
If the impurity has a higher boiling point then the boiling point of the mixture will also be slightly higher, and vice versa.
Freezing point is the point at which a liquid turns into a solid What effect can change the freezing point?
Changing the pressure can affect the freezing point of a substance. Generally, an increase in pressure will lower the freezing point, while a decrease in pressure will raise the freezing point. The presence of solutes or impurities in the liquid can also change the freezing point.
What is the purpose of a freezing point apparatus in determining the freezing point of a substance?
The purpose of a freezing point apparatus is to accurately measure the temperature at which a substance changes from a liquid to a solid state, known as its freezing point. This information is important for identifying and characterizing the substance.
What is its melting point when the freezing point of a substance is 68C?
The freezing point is 680C
Will a 0.5 M solution have a higher freezing point than a 0.75 M solution of the same substance?
No, the 0.75 M solution will have a higher freezing point. The freezing point depression is directly proportional to the molality of the solution, so a higher concentration solution will have a greater effect on lowering the freezing point.
what is the freezing point in the desert?
The "freezing point" of any particular pure chemical substance is the same everywhere, in the desert as much as anywhere else, except for a slight effect of prevailing pressure!
Can a volatile impurity increase the boiling point of a substance?
No, a volatile impurity will lower the boiling point of a substance by disrupting the uniformity of the liquid phase. This causes the solution to boil at a lower temperature compared to the pure substance.
Are the melting point of solid and freezing point of liquid of a substance different?
yes the melting point of solid and freezing point of liquid of a substance is differ but in the case of water the melting and freezing point is same.
The freezing point of a substance is?
The freezing point of water in Celsius is 0 degrees Celsius. The freezing point in Fahrenheit is 32 degrees Fahrenheit.
