How is the melting point of asolid and boiling point of a liquidaffected when impurities are added to the substances?
Adding impurities lowers the melting point and raises the boiling point.
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.
Does sugar affect melting point?
No, sugar does not affect the melting point. The melting point of a substance is determined by its chemical composition and structure. However, adding sugar to a solution can affect its boiling point, but that is a different property.
How does salt raises the melting point of water?
It doesn't increase the melting point of ice, instead, it lowers it. When a solute (which is the salt) is added to a solvent (which is what dissolves it), the boiling point is increased while both the freezing and melting points are decreased. This is evident in the boiling point elevation and the freezing/melting point depression system.
Does the presence of water raise the melting point of felsic magma?
No. Water lowers the melting point of magma, both mafic and felsic.

Can boiling point of acetone be lowered if placed in a vacuum?
Yes, the boiling point of acetone can be lowered if placed in a vacuum, as reducing the pressure lowers the boiling point of a substance. This is because at lower pressure, there is less external pressure pushing down on the liquid molecules, allowing them to escape into the vapor phase more easily.
What are the effects of pressure on melting boiling points of a substance?
Increasing pressure generally increases the melting and boiling points of a substance. This is because pressure forces molecules to be packed closer together, making it harder for them to break free from each other in the solid or liquid phase. Conversely, decreasing pressure lowers the melting and boiling points.
How do the melting and boiling points of water differ from those of a sugar water solution?
The melting and boiling points of water are higher than those of a sugar water solution because the presence of sugar disrupts the hydrogen bonding between water molecules. This disruption lowers the melting and boiling points of the solution compared to pure water.
How does adding salt to water affect the way water changes temperatures?
Adding salt to water rises its boiling point but lowers the melting point
Does sugar affect melting point?
No, sugar does not affect the melting point. The melting point of a substance is determined by its chemical composition and structure. However, adding sugar to a solution can affect its boiling point, but that is a different property.
How does the addition of impurities to a metal affect its melting point?
The addition of impurities to a metal lowers its melting point by disrupting the regular arrangement of metal atoms. These disruptions hinder the ability of the metal atoms to align properly and form a solid structure, making it easier for the metal to melt at a lower temperature.

When a solute (which is the salt) is added to a solvent (which is what dissolves it), the boiling point is increased while both the freezing and melting points are decreased. This is evident in the boiling point elevation and the freezing/melting point depression system.
What do you think salt does to the melting point of ice?
Salt lowers the melting point of ice.
What lowers the melting point in alumina?
Cooling the heat source
What is the tendency of a solute to change the melting point of a solid?
Boiling point elevation
