What else can I help you with?
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.
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.
Effects of impurities and pressure on melting point of water?
Impurities decrease the melting point of water by interfering with the crystal lattice structure. Pressure can increase the melting point of water by stabilizing the solid form due to the reduced volume and increased interactions between molecules. Overall, impurities tend to lower the melting point, while pressure tends to raise it.
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.
What effect has impurities on melting and boiling points of a pure substance?
Impurities can lower the melting point and raise the boiling point of a pure substance. This occurs because impurities disrupt the crystal lattice structure of the substance, making it harder for the molecules to align and transition between solid and liquid states. The presence of impurities can also alter the intermolecular forces between molecules, affecting the energy required for melting and boiling.
Do pure substances have a fixed boiling and melting point?
yes they have
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
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 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 impurity effects boiling point?

Do elements compounds and mixtures have fix melting and boiling point?
Elements have fixed melting and boiling points, while compounds have varying melting and boiling points depending on their composition. Mixtures do not have fixed melting and boiling points, as they are composed of multiple substances which each have their own individual melting and boiling points.
Effects of impurities and pressure on melting point of water?
Impurities decrease the melting point of water by interfering with the crystal lattice structure. Pressure can increase the melting point of water by stabilizing the solid form due to the reduced volume and increased interactions between molecules. Overall, impurities tend to lower the melting point, while pressure tends to raise it.
Do simple molecular substances have high or low melting and boiling points?
Simple molecular substances typically have low melting and boiling points. This is because the weak intermolecular forces, such as London dispersion forces, in simple molecular substances are easily overcome compared to the stronger bonds in ionic or metallic substances.
