Nitrogen has a lower melting point than iron and water because it is a diatomic molecule with weaker intermolecular forces holding its molecules together compared to the strong metallic bonds in iron and hydrogen bonds in water. This results in nitrogen melting at a much lower temperature compared to iron and water.

How do you think the melting point of salt water compares to that of pure water?
The melting point of saltwater is lower than that of pure water. This is because the presence of salt disrupts the hydrogen bonds between water molecules, making it harder for the water to freeze.
Why is melting point of ammonia lower than water?
The melting point of ammonia is lower than that of water because ammonia molecules are lighter and have weaker intermolecular forces compared to water molecules. This results in ammonia being a gas at a lower temperature than water, making its melting point lower.
What has the lowest melting point water timber or plastic?
Of the three options, plastic has the lowest melting point. Different types of plastics have varying melting points, but in general, they melt at lower temperatures compared to both water and timber.
What is the melting point of water at 5000 meters?
The melting point of water at 5000 meters is slightly higher than at sea level due to the lower atmospheric pressure. At this altitude, water will freeze at around 0.2 degrees Celsius.
How does water affect the melting temperature of a mineral?
Water can lower the melting temperature of a mineral by acting as a flux or catalyzing agent, allowing atoms to move more freely and reducing the energy required for melting. This can lead to the formation of new minerals or phases at lower temperatures than would occur without water present.
When ethylene glycol is added to water the melting point of water is?
Ethylene glycol is antifreeze. The mixture has a lower melting point than pure water.
Why does plastic have a lower melting point than water?
Water can't melt!!!
How do you think the melting point of salt water compares to that of pure water?
The melting point of saltwater is lower than that of pure water. This is because the presence of salt disrupts the hydrogen bonds between water molecules, making it harder for the water to freeze.
What are the boiling and melting point's of salty water?
That depends on how much salt is dissolved in the water. Generally, the boiling point will be higher than for pure water, and the melting point will be lower than for pure water.
How does sprite melt fast?
It has a lower melting point than water.
Lower the melting point of wax?
To lower the melting point of wax, you can consider adding a small amount of mineral oil or vegetable oil to the wax before melting it. This will decrease the overall melting temperature of the wax. Alternatively, you can mix the wax with a lower melting point wax to create a blend with a reduced melting point.
When are oil baths and water baths used respectively for melting point determination?
Oil baths are typically used for high-temperature melting point determinations, where the sample needs to be heated to a temperature above the boiling point of water. Water baths, on the other hand, are used for lower temperature melting point determinations, as water has a lower boiling point compared to oil.
Which is colder frozen water or frozen salt water at melting points?
The freezing point of salted water is lower compared with the freezing point of pure water. So when melting frozen salt water is colder.
How does melting point change as the water content of rocks increases?
As the water content of rocks increases, the melting point typically decreases. This is because the presence of water lowers the melting point of minerals in the rocks by acting as a flux that promotes melting. The addition of water creates a eutectic point where the rock will begin to melt at a lower temperature.
What is the effect of the salt by usingthe concept of melting point?
Salt water has a lower freezing point and a higher boiling point.
A wet rock generally melts at a lower temperature than a dry rock true or false?
True. Water has a lower melting point than most rocks, so when a rock is wet, the presence of water can lower the overall melting point of the rock.
Why is the melting point of impure water lower than the melting point of pure water plus how can this be explained?
Impurities disrupt the crystal structure of water, making it harder for the molecules to arrange themselves into a solid lattice. This disruption weakens the forces holding the molecules together, resulting in a lower melting point for impure water compared to pure water.
