Substances may contain more elements than the other substance, meaning that it would take more energy (heat) to break the bonds of the substance as opposed to the other substance. Because these bonds must break in order to change phases, it would take more energy to dismantle the larger substance. Another thing that affects melting points is the types of bonds that connects the atoms to each other. Double bonds take more energy to break than single bonds. Triple bonds take more energy than double bonds so that could also account for the differences in melting points between two substances.

What causes different melting points?
Different melting points are caused by variations in molecular structures and intermolecular forces between substances. Substances with strong intermolecular forces will have higher melting points, while substances with weaker forces will have lower melting points. Additionally, factors such as molecular weight, shape, and polarity also contribute to the melting point of a substance.
Why do different materials have different melting points?
Different materials have different melting points due to variations in the strength of intermolecular forces between their particles. Substances with strong intermolecular forces require more energy to overcome these forces and transition from solid to liquid states, resulting in higher melting points. Conversely, substances with weaker intermolecular forces have lower melting points.
How would you find the relative melting points of a group of substance?
You can compare the relative melting points of substances by looking at their chemical structures, molecular weights, and intermolecular forces. Substances with stronger intermolecular forces (such as hydrogen bonding) typically have higher melting points compared to those with weaker forces. Experimentally, you can also perform melting point tests to directly compare the melting temperatures of the substances.
Why two different substances have different melting point?
Different substances have different melting points because the strength of intermolecular forces (such as hydrogen bonding, dipole-dipole interactions, and London dispersion forces) vary between substances. Substances that have stronger intermolecular forces require more energy to overcome them, resulting in a higher melting point. Conversely, substances with weaker intermolecular forces have lower melting points as they require less energy to transition from solid to liquid state.
Do liquids have melting points?
NO!!! However, on change of physical state;- solid to liquid it is 'melting' liquid to solid it is 'freezing' Similarly liquid to gas it is evaporation/boiling gas to liquid it is condensation. Different substances have different temperature for change of physical state. Water being the scientific standard has; - melting/freezing at 0oC boiling/evaporation at 100oC

Are melting points of molecular substances higher than those of ionic substance?
Ionic substances have higher melting points.

When does a substance hit its melting point?
Different substances have different melting points. You'd need to specify the substance to learn the temperature at which that particular substance melts.
At which temperature does a solid changes to a liquid?
Substances have different melting points. When a substance reaches it melting point it will begin a phase change. Wikipedia's chart for elements of melting points. http://en.wikipedia.org/wiki/List_of_elements_by_melting_point
Do proteins have definite melting points?
Different proteins have different melting points.
What two uses do chemist put the melting points of substances?
- a substance can be identified after the melting point because it is a specific physical characteristic- melting points knowledge is necessary for technology

Do simple molecular substances have high or low melting and boiling points?
Simple molecular substances typically have low melting and boiling points. This is because the weak intermolecular forces, such as London dispersion forces, in simple molecular substances are easily overcome compared to the stronger bonds in ionic or metallic substances.
Why substances have different melting points?
just because accept it ok!
