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.

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.
What is the effect of impurities on boiling point?
i have worked with my students and found water to boil at 97 degrees Celsius.this water had carbonated and bicarbonates as it was ordinary water.
Is the melting point of impure water lower or higher than freezing point?
The melting point of impure water is lower than the freezing point. Impurities disrupt the crystalline structure of water, making it harder for the water molecules to align and freeze. This results in the impure water needing to be cooled to a lower temperature before it freezes.
Why might the typical boiling point change?
The typical boiling point of a substance can change due to factors such as changes in atmospheric pressure, the presence of impurities in the substance, and variations in the composition of the substance itself. Additionally, the boiling point of a substance can be affected by the altitude at which it is being boiled.
What can be said about boiling point of a liquid?
The stronger the intermolecular forces in a liquid, the higher the boiling point. -APEX
What may happen to the boiling point of a substance if there are impurities present?
The boiling point won't decrease
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.
How does impurities affect the boiling point of liquid?
Let's say substance A is the substance and substance B is the impurity. The boiling point of the mixture would be somewhere between that of A and B, depending on the amount of impurities in the mixture.
How does pressure and impurities affects boiling point?
Boiling is used to describe a change of state of a pure liquid to vapour phase. The particular temperature at which this change of state occurs is defined as the boiling point of that specific liquid. Now the question is will addition of impurities have any effect on the boiling point of water. The addition of impurities such as salt or sugar to pure water raises its boiling point.
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 may happen to the boiling point of a substance if there are impurities present. Explain in terms of the nature of impurities.?
The boiling point of a substance may increase if impurities are present. This occurs because impurities disrupt the regular arrangement of particles in the substance, making it harder for the substance to change phases. As a result, more heat is needed to overcome these disruptions, leading to an elevation in the boiling point.
What is the effect of impurties in boiling point?
Impurities in a substance can raise or lower its boiling point, depending on the nature of the impurities. When impurities are added to a liquid, the boiling point of the solution increases due to the decrease in vapor pressure. This phenomenon is known as boiling point elevation. Conversely, impurities in a liquid can also lower the boiling point by disrupting the intermolecular forces between the solvent molecules, causing a decrease in boiling point, known as boiling point depression.
How does one increase the melting or boiling point of a substance?
Add impurities (salt and others) to the substance.
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.
What may happen to the boiling point of the substance if there are impurities present?
The presence of impurities typically raises the boiling point of a substance. This is due to the impurities disrupting the crystal lattice structure and reducing the ability of the liquid to vaporize, thus requiring a higher temperature to achieve boiling.
What is the effect of impurities on boiling point?
i have worked with my students and found water to boil at 97 degrees Celsius.this water had carbonated and bicarbonates as it was ordinary water.
Is the boiling point of a pure substance the same as an impure substance and why?
Adding impurities changes both boiling points and freezing points. The added material has its own chemical interactions with the solvent to which it is added. In order to boil, a substance must overcome the chemical attraction between its own constituent atoms or molecules. If there are also other atoms or molecules to which a constituent atom or molecule of a given substance is also attracted, the boiling point will therefore be higher. No it's not the same it dip pends on what the substance is.
