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 is the melting point H20?
H2O is water. The melting point of water is 0oC or 32oF
Effects of impurities and pressure on melting point of water?
Impurities decrease the melting point of water by interfering with the crystal lattice structure. Pressure can increase the melting point of water by stabilizing the solid form due to the reduced volume and increased interactions between molecules. Overall, impurities tend to lower the melting point, while pressure tends to raise it.
Why does hydrogen bonding raise the melting and boiling point of water?
Hydrogen bonding in water causes molecules to be attracted to each other, requiring more energy to overcome these attractions during melting or boiling. This results in higher melting and boiling points for water compared to molecules that do not participate in hydrogen bonding.
What is the point of water called?
Its melting point
Why is melting point for water higher than alcohol?
Water has stronger hydrogen bonds between its molecules compared to alcohol, leading to a higher melting point. These hydrogen bonds require more energy to break apart, resulting in a higher melting point for water than alcohol.

How do you think the melting point of salt water compares to that of pure water?
The melting point of salt water is even lower than pure water.
Why is the melting point of impure water lower than the melting point of pure water plus how can this be explained?
the melting point of IMPURE water is lower because excess chemicals and sediments (and whatever else making it impure) get in the way of the water freezing directly by making it so that when the the water froze, it also had to freeze the sediments and chemicals (or else it wouldn't be frozen)
Why does octane have a higher boiling point then water?
Octane is a straight chain molecule with a large surface area and stacks easily with other octane molecules. This increases the strength of the London dispersion forces that keep the octane molecules attracted to each other. The London dispersion forces on octane are greater than for smaller straight chain molecules because octane is both heavier and has more electrons that make it more polarizable.
What's the melting point of water in Celsius?
The melting point of water is zero degrees Celsius.
What has high melting point HCL HBr H2O Br2?
The compound with the highest melting point among HCl, HBr, H2O, and Br2 is H2O (water). Water has a high melting point due to its strong hydrogen bonding, which requires a significant amount of energy to break apart the bonds between water molecules.
Explain the melting point of hydrogen sulphide?
It is not easy to "explain a melting point" without having some context for the question or a compound to compare it to. What I can say is... 1. The melting point of hydrogen sulfide is -82 degrees C. 2. H2S is a polar molecule (has a similar shape to water) and so will have a higher melting point than similarly sized atoms or molecules that are not polar like argon (MP = -189 degrees C) or O2 (MP = -218 degrees C). 3. Lacking an O-H, F-H, or N-H bond, H2S cannot form hydrogen bonds with other H2S molecules, so it won't have as high a melting point as H2O (MP = 0 degrees C), even though H2O is a smaller molecule (weaker dispersion forces) and both are polar. 4. Even though H2S is polar it is relatively small, which means it will have only weak dispersion forces contributing to holding the molecules together. There are plenty of molecules out there like Br2 (MP = -7 degrees) that are non-polar but still have higher melting points. This is because they have big, polarizable electron clouds that make the dispersion forces that hold them together stronger than the combination of dipole-dipole and dispersion forces that hold H2S molecules together. So although I do not exactly think I have explained the melting point of hydrogen sulfide, hopefully I have given you enough context to show you why it has such a low (-82 degrees C) melting point.

What kind of property is melting point and freezing point of water?
The melting point and freezing point of water are physical properties. The melting point is the temperature at which ice (solid) changes to water (liquid), while the freezing point is the temperature at which water (liquid) changes to ice (solid).
Why does salt lower ice melting point?
I'll give two explanations. The first explanation needs an understanding of thermodynamics, the second one is easier. The addition of salt to water results in an increase in "entropy". This results in a lowering of the freezing point. That means the melting point is lower too. Unfortunately, you need to go through some mathematics to understand this explanation properly. So, you may prefer this explanation: When water freezes it forms ice (pure water). The water molecules still in the liquid phase have salt ions mixed in, reducing the concentration of water molecules. So, there's a reduction in water molecules going from liquid phase to the solid at the surface between liquid and ice. That means its harder to form ice and the melting point is lower. The lower melting point is simply because the concentration of water molecules in a salt solution is lower than in pure water. It's not because the salt "blocks" the path of water molecules or affects the chemical bonds. In fact, many different substances can lower the melting point.
