How does branching affect the boiling point of a substance?
Branching in a molecule generally lowers the boiling point of a substance. This is because branching reduces the surface area available for intermolecular forces to act upon, making it easier for the molecules to escape into the gas phase.
Does the boiling point increase with pressure?
Yes, the boiling point of a substance increases with an increase in pressure.
Does the boiling point increase with molar mass?
Yes, generally speaking, the boiling point of a substance increases with its molar mass.
How could a liquids boiling point be used to determine if it is a mixture or a pare substance?
pure substances have a distinct boiling point. Adding more heat just makes the substance boil faster but the temperature stays the same. A mixture does not have a distinct boiling point. Adding more heat will make the temperature increase.
How can one determine the boiling point of a substance?
The boiling point of a substance can be determined by heating the substance and measuring the temperature at which it changes from a liquid to a gas. This temperature is known as the boiling point.

Does the boiling point increase with pressure?
Yes, the boiling point of a substance increases with an increase in pressure.
If you increase the pressure the boiling point will increase or remain same?
If you increase the pressure, the boiling point of a substance will increase. This is because higher pressure leads to stronger intermolecular forces, requiring more energy to overcome them for the substance to boil.
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.
Does the boiling point increase with molar mass?
Yes, generally speaking, the boiling point of a substance increases with its molar mass.
How does one increase the melting or boiling point of a substance?
Add impurities (salt and others) to the substance.
What processes is most affected by pressure freezing or boiling or melting?
Boiling and freezing points of a substance are affected by pressure. An increase in pressure raises the boiling point and lowers the freezing point of a substance. Melting point is not significantly affected by pressure.
How could a liquids boiling point be used to determine if it is a mixture or a pare substance?
pure substances have a distinct boiling point. Adding more heat just makes the substance boil faster but the temperature stays the same. A mixture does not have a distinct boiling point. Adding more heat will make the temperature increase.
Is the boiling point of a substance an example of a chemical property?
The boiling point of a substance is an example of a physical property of that substance.
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.
How can one determine the boiling point of a substance?
The boiling point of a substance can be determined by heating the substance and measuring the temperature at which it changes from a liquid to a gas. This temperature is known as the boiling point.
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.
