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.


What temperature will a substance melt if the atmospheric pressure is 1.2?

Leaving aside the obvious deficiencies in the question (1.2 WHAT? What substance?)... For most substances pressure has only a tiny effect on the melting point, and enormous pressures are required to change the melting point significantly (in contrast to boiling point, where pressure has a relatively much greater effect).


Properties that affects the melting and boiling points of a molecule?

The melting point and boiling point of a substance come under the category of phase changes. And the temperature at which these phase changes occur are related to the intermolecular forces holding the molecules of the substance together.


What physical effect can change the boiling of substance?

Pressure


What is the effect when you apply heat to substance?

When heat is applied to a substance, it causes the molecules in the substance to gain energy and move faster, leading to an increase in temperature. This can result in phase changes, such as melting or boiling, depending on the substance. In chemical reactions, heat can also provide the activation energy needed for the reaction to occur.


How does phase change effect the mass of a substance?

A phase change does not affect the mass of a substance because mass is a constant property of matter. During a phase change, such as melting or boiling, the substance's molecular arrangement changes, but the total mass remains the same.


Did corn meal affect the boiling temperature of water the same as sugar?

Each substance has a different effect on the boiling point.


Does acidity effect the boiling point?

No, acidity does not directly affect the boiling point of a substance. The boiling point is mainly determined by the intermolecular forces within a substance and the external pressure exerted on it. Acidity may affect the chemical properties of a substance, but it does not have a direct impact on its boiling point.


Does melting point and boiling point of liquid changes from altitude to altitude?

The boiling point depends on altitude (pressure). The effect on the melting point is not significant.


Why vacuum reduces melting point?

Reduced pressure in a vacuum lowers the boiling point of a substance by decreasing the pressure on the liquid, causing it to vaporize more easily. This leads to a decrease in the melting point as well, as the substance transitions from solid to liquid more readily in a vacuum environment.


What is the melting and boiling points of magnesium and chloride?

The melting point of magnesium is 1,202 degrees Fahrenheit (650 degrees Celsius) and its boiling point is 1,994 degrees Fahrenheit (1,090 degrees Celsius). The melting point of chlorine is -150.7 degrees Fahrenheit (-101.5 degrees Celsius) and its boiling point is -29.27 degrees Fahrenheit (-34.04 degrees Celsius).


What effect would increasing the quantity of paradichlorobenzene have on the melting point temperature?

The melting point of the substance should not change as all substances have specific melting, boiling, condensation, and freezing points. It would, however, require more energy (in this case, heat) to melt the increased quantity of paradichlorobenzene in the same amount of time.
