The intermolecular forces are weakened.

∙ 15y agoIn a solid, the bonds between molecules are rigid and tightly bonded. When heat is added to the molecules, its kinetic energy increases. Causing the molecules to vibrate more, loosening the bonds. Once the bonds are loose enough, the molecules can move over and around each other, unlike its previous state being rigid and tight. So the bonds between the molecules when a substance is melted become weaker, looser. In a solid, the bonds between molecules are rigid and tightly bonded.

What will happen when atom and molecules of substance melt freeze boil or condense?
When a substance melts, the molecules move more freely and when it freezes, they move more slowly. When a substance boils and becomes a vapor (gas), the molecules again move faster than when in the liquid state, and when the vapor condenses, the molecules move slower.
What substance is a mixture of molecules?
The Type of substance of a molecule would be an element.
What is a metabollism?
Metabolize is a verb. It means that molecules are being built up "anabolism" or being torn apart atom by atom "catabolism".
How atom and molecules are important to cell processes explain?
why atom and molecules are important to cell processes explain
What determines the electron-group geometry of a molecule?
Electronegativity of each atom is what determines the electron distribution of a bond. The electronegativity of an atom affects its distance in its valence electrons and its atomic number.
What happens to the atom or molecules of a substance if it melts?
Nothing. Melting is a physical change and does not alter the chemical composition of a substance.
What will happen when atom and molecules of substance melt freeze boil or condense?
When a substance melts, the molecules move more freely and when it freezes, they move more slowly. When a substance boils and becomes a vapor (gas), the molecules again move faster than when in the liquid state, and when the vapor condenses, the molecules move slower.
Is the smallest particle of a substance that is still that substance having all the properties of that substance?
If the substance is an element the answer is an atom. If the substance is a compound the answer is a molecule.
What will happen to the atom or molecule of a substance when it boil?
the atoms and molecules will vibrate, causing the substance to heat up (friction causes heat, the molecules and atoms will rub together, causing friction). I hope this helped!!!!!n_n when a substance reaches its boiling point naturally the intermolecular force becomes weak and the substance gets converted from one form to another..
What substance is a mixture of molecules?
The Type of substance of a molecule would be an element.
1 mole of Pb atom is6.023x10?
1 mole of any substance has 6.022 x 1023 atoms or molecules of that substance
What is an Melting point?
An atom itself does not melt. The substance made out of atoms melts when it gets to hot in temperature, and the increased energy in the atoms causes the substance to fall apart somewhat.
What is an atoms melting point?
An atom itself does not melt. The substance made out of atoms melts when it gets to hot in temperature, and the increased energy in the atoms causes the substance to fall apart somewhat.
When a substance is raised to its melting teperature what happens to the atom or molecules?
The inter-molecular bonds between the atoms/molecules are broken, releasing the atoms/molecules from a ridged structure to a freely moving mass.
Why does an object float in water?
molecules make an object float the airs density has gases that react to substance and then change phase an element has only 1 kind of atom and that atom gets
What is substance made up of one atom called?
If you mean a substance made up of only one atom, that would be a mono-atomic element, and would be a noble gas.If you mean a substance made of only one kind of atoms, that would be an element.
What is the melting point temperature?
The temperature at which the solid melts, which remains constant until all of the substance is melted.
