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 else can I help you with?
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.
Effect of impurities on melting point and melting point?
According to RAOULT, when two different metals of different melting points are melted or alloyed there melting points considerably change. So,according to the percentage of impurities, the melting points either increase or decrease.
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.
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).
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.
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.
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.
What is the effect of impurities on boiling point?

Does soluble impurities effect boiling?
yes
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.
Effect of impurities on melting point and melting point?
According to RAOULT, when two different metals of different melting points are melted or alloyed there melting points considerably change. So,according to the percentage of impurities, the melting points either increase or decrease.
How does impurities in water effect its boiling point?
Depending on what is in it, the boiling point will either rise or fall.
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.
What effect would contaminating the sample with an insoluble impurity have on the melting point?
Soluble impurities (that is, impurities that are included within the crystal matrix) tend to lower the observed melting point and broaden the melting point range. Insoluble impurities have no effect on the melting point. Found from website: http://swc2.hccs.edu/pahlavan/2423L1.pdf
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.
What is the effect of impurities on the melting point of ice and the boiling point of water?
The freezing point of water decreases when the number of dissolved molecules (or better particles) in the solvent increases. This is called freezing point depression and you can easily find the relation between the quantity of particles dissolved and the freezing point on Wikipedia.
What is the effect of impurities on boiling point of different chemicals?
It varies. A saturated solution of NaCl in water increases the boiling point, higher than 100oC. I suppose most impurities increase the boiling point.
