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 are the effect of impurities on the freezing point of water?
An impurity, such as salt lowers the freezing point of water by interfering with the lattice structure water makes with hydrogen bonding at it's freezing point.
What occurs at the freezing point of a substance?
At the freezing point a substance become a solid.
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.
Is the melting point the same temperature as the freezing point for a substance?

What is its melting point when the freezing point of a substance is 68C?
The freezing point is 680C
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!
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.
What freezing point of a substance is the same as its?
(Melting Point)
A liquid changes back into a solid by freezing at what point?
The FREEZING POINT ----- which for a pure substance (as opposed to a mixture)is the same thing as the melting point since they are both the point at which the liquid phase of a substance would be in equilibrium with the solid. For a mixture, the two would be different and you would get a freezing point range that started at the freezing point and ended at the melting point
Does sugar afect how fast an ice cube melts?
Any impurity decrease the freezing point of water.
Is the melting point the same teperature as the freezing point for a substance?
Yes, when the substance is pure
True or False- The freezing point of a substance is equal to the melting point of a substance?
It is true.
