what are some of the factors that affect melting point besides, impurities, pressure, and having a wet solution?
For a single compound or solvent, pressure and dissolved solute concentration (including impurities) are the important variables. Of course, the melting point depends very much upon the material chosen.
I don't know what you mean by the "wet solution" effect.
well if it is wet then the solution will contain some impurities from the water or which ever other compound is added to the solution.
A wet solid is likely to be impacted to a large extent in the melting point. But it isn't the impurities that you worry about so much with the melting point of solids. It's the water.
Besides impurities, pressure, and the presence of a wet solution, there are several other factors that can affect the melting point of a substance. These factors include:
1. Molecular size and structure: The size and shape of molecules can influence their melting point. Generally, larger molecules have higher melting points because they have more intermolecular forces holding them together. Linear-shaped molecules also tend to have higher melting points compared to branching or more complex structures.
2. Intermolecular forces: The type and strength of intermolecular forces (forces between molecules) play a significant role in determining the melting point. Substances with strong intermolecular forces, such as hydrogen bonding or dipole-dipole interactions, tend to have higher melting points.
3. Molecular polarity: Molecules with polar bonds or an overall molecular polarity tend to have higher melting points. This is because polar molecules experience stronger intermolecular forces, which require more energy to break and transition from the solid to liquid phase.
4. Crystalline structure: The arrangement of molecules in a solid crystal lattice also affects the melting point. Crystals with highly ordered structures typically have higher melting points compared to amorphous solids or substances with less organized arrangements.
5. Presence of impurities: While impurities can affect the melting point, they can also lower or increase it depending on the specific impurity. In some cases, impurities disrupt the crystal lattice, leading to a lower melting point, while in others, impurities form additional intermolecular forces that raise the melting point.
To determine the effect of these factors on the melting point, it is important to consider the substance's molecular characteristics, intermolecular forces, molecular structure, and the influence of any impurities present.
