Will there be effect on melting or boiling point of a substance if another substance is added to it?
Yes, impurities have important effects on the melting and boiling point of materials.
Effects of impurities and pressure on melting point of water?
melting point decreases with pressure and increases with impurities (like saw dust). boiling point increases with impurities and also increases with pressure.
Do pure substances have a fixed boiling and melting point?
yes they have
How does impurity effects boiling point?
Impurities will usually lower the melting point of an organic compound. Impurities also increase the range of melting points in the compound. This means the temperature needed for melting isn't consistent.
Explain why the boiling point and the melting point can be used to help identify substances?
100 degrees mate. 100 degrees Celsius is the boiling point for pure water at 1atm or sea level. The boiling point is useful in identifying chemical compounds. Chemical compounds have different boiling points that are specific to it' s chemical composition. If you know what the boiling point or melting point is you can also tell if your compound is pure, as any impurities will change these.
Why do impurities lower the boiling point of a pure substance?
The presence of the impurities will cause the boiling points to rise (also the melting points to fall). When you add the impurities, the substance doesn't remain pure affecting the boiling point to increase because now, more energy is required to boil the liquid with impurities. The melting points fall because impure substances require less energy to separate the particles.
How does the addition of impurities to a metal affect its melting point?
generally addition of impurities lowers the melting pointand increases the boiling point

yes they have
How does one increase the melting or boiling point of a substance?
Add impurities (salt and others) to the substance.
To increase Melting and boiling point of Zinc what is to be done?
To increase MP and BP point of Zinc u should add some impurities in it. The addition of impurities always decreases the melting point .
Why a sharp melting point could not be obtained always?
the melting point of pure substances is always being sharp. it means that the boiling point it have it will boil at that point not some up or down but on same temperature in other words we say that it has no impurities because of impurities it boiling point varies and it has many other components and boiling point of every component is different so that why the boiling point of impure compounds varies or it don t have exact value and the pure compounds have same elements combine together and every molecule boil at particular point so it has sharp melting point or exact point

What are the characteristic of pure substances?
The characteristics of pure substances are:fixed melting pointfixed boiling pointsfixed valencyfixed densitystability
Is a sharp melting point for a crystalline organic substance always indicates a pure single compound?
Nope; not always. So the answer would be false. You have to realize that there might be impure substances mixed. Likewise impure substance can either lower the melting point or increase it :)M. Bilal :)
