The kinetic theory states that when a solid is heated the bonds between the particles are loosened thus making it a liquid.
As the kinetic energy increases, the temperature rises, and as the kinetic energy of the molecules decreases the temperature decreases.
The movement of molecules or atoms are amplified and the bonds are broken.

Boiling water can be either thermal energy or kinetic energy dependent upon how it's used. If it is used to heat up another object (thereby transferring energy in that manner) it is thermal; if the water vapor from the boiled water is used to say, run a turbine, it would be kinetic in that sense. Chances are, for most cases involving boiling water, or more specifically the water vapor produced by it, the energy associated with that will be kinetic.
Heat raises the kinetic energy within the molecule, this causes internal shaking at a molecular level. The shaking weakens the bonds, thus lowering the activation energy of the reaction.
Heat cause kinetic energy within an element or compound.

None, starch will decompose fully before it boils. :)

Any impurity(something that does not belong to the compound but is present in the compound) has effects on the boiling and melting points of a given substance. From yahoo answers,An impurity causes the melting point to deviate from the standard. Actually, it makes the magnitude of the melting point lower. For example, the melting point of benzoic acid is 122.4 degree Celsius. When we did this in the laboratory, we got 120 degree Celsius because of the impurity present which is sodium sulfate.An impurity also causes the melting point to become a melting range. The melting point is not anymore sharp, but a range of values. The more impurities present, the greater the range of values. For example, when we purified crude acetanilide via recrystallization, we obtained a melting range of 105-116 degree Celsius. By the way, the standard melting point of acetanilide is 113-115 degree Celsius.So basically, those are the two effects that impurities have on melting point iof a pre compound. I learned that it is because the impurities "defect" the crystal lattice of the compound. A pure compound is a structure of high molecular symmetry. An impurity is rather assymetrical, or is a poorly organized structure. If the impurites are present with the pure compound, the melting point will deviate because melting point is also dependent on the high symmetry and organization of molecular structures, just as the vapor pressure. This is the principle involved in Sublimati
Heat energy is the stimulation of molecular motion. Anything that adds energy to a substance can increase its temperature, eventually causing molecular decomposition or a change in the phase of its elements (solid to liquid, liquid to gas, gas to plasma).
By melting
Ionic bonds require relatively high energies to be broken compared to the weaker hydrogen bond and van der Waals forces. Ionic compounds will thus have higher melting points than polar and organic compounds of similar molecular weight.

Melting causes an igneous rock to form into lava/magma.
