How does impurity effects boiling point?
Impurities will usually lower the melting point of an organic compound. Impurities also increase the range of melting points in the compound. This means the temperature needed for melting isn't consistent.
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 raises the melting point of most materials?
Pressure of 100s of megapascals on the material noticeably raises melting point. In a solution, a solute lowers melting-freezing point. To raise the solution's point, it should need to be taken past saturation such that solvent and solute trade amounts if the former solvent had a greater melting point than the solute. However, this solution's melting point is still lower than each compound's alone. Olighomers can be transmuted into polýmers with a hardier melting point or range. Polar isomers and polar-group-substituted polýmers are more resistant to melting than their covalent analoghs, as are compact and sýmmetric (more cubic) allotropes and polýmorfs most often after pressure. Neutron-heavy isotopes also melt at a greater temperature. The former three are not strictly the same material.
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.
What muscle raises the trunk after sitting?
Gluteus maximus.

How do you do the project to How does the salt effect the boiling temperature of water?
Because the salt is an impurity it raises the boiling point by density differences
How does the the compound eye work?
raises accruacy by 30% in battle

What determines if water is melting or freezing at 0 degrees Celsius?
if the temperature raises then water is melting (ice becomes water),if the temperature falls then it's freezing (water becomes ice)

What prevents the outer core from changing to a gas or the inner core from melting to a liquid?
The immense pressure on the core raises melting and boiling points of the metal, allowing the outer core to reman liquid and the inner core to remain solid.
Calculate the mass of a mole of a compound that raises the boiling point of water to 100.78C at 101.3 kPa when 51 g of the compound is dissolved in 500 grams of water?
67 g/mol
What are the effects of impurities on melting point?
Impurities in a liquid raise its melting point. For example, putting SALT on Ice raises the melting point above 32 F. This causes the Ice to melt, because, consequently its FREEZING point has been LOWERED. So, at 32F ice plus salt is just liquid SALTWATER.
Why does most of the rock in the asthenosphere remain solid?
The rock in the asthenosphere is under immense pressure from the overlying rock. Increased pressure raises the melting point of most substances.
Do continents shrink after ice age because of ice melting into water?
Yes. The ice melts and raises sea levels. Areas that were once dry land are submerged.
