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.

How would you find the relative melting points of a group of substance?
Look at all of the different substances melting points and find the average
Why do different materials have different melting points?
The melting point depends on the strengths of the forces between the particles. Different substances have different strengths and types of force.
Do simple molecular substances have high or low melting and boiling points?
Yes, molecular solids have relatively low melting points.
What is the conclusion of melting and boiling point?
the conclusion is that the melting points and boiling points of various substances or chemicals are different. Some have m.p. but some don't have while some have b.p. but some don't have.it varies from chemical to chemical.
Effect of impurities on melting point and melting point?
According to RAOULT, when two different metals of different melting points are melted or alloyed there melting points considerably change. So,according to the percentage of impurities, the melting points either increase or decrease.
How would you find the relative melting points of a group of substance?
Look at all of the different substances melting points and find the average
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.
Why do different materials have different melting points?
The melting point depends on the strengths of the forces between the particles. Different substances have different strengths and types of force.
Do simple molecular substances have high or low melting and boiling points?
Yes, molecular solids have relatively low 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
What is the conclusion of melting and boiling point?
the conclusion is that the melting points and boiling points of various substances or chemicals are different. Some have m.p. but some don't have while some have b.p. but some don't have.it varies from chemical to chemical.
Why substances have different melting points?
just because accept it ok!
Where are the boiling points and melting points of different substances?
M.P=min TEMP From where a solid begins to melt. B.P=MIN TEMP FROM WHERE( MELTED SOLID) OR LIQUID BEGINS to boil.
What is a temperature at which a substance changes from a solid to a liquid?
It matters what the object is. All substances have different melting/freezing points. (water is 32 degrees)
