Answer:
<u>Kinetic particle theory</u>
Arrangement and motion of solid particles
-> Solid particles are packed closely with each other in an orderly manner. They vibrate vigorously in their fixed positions.
Arrangement and motion of liquid particles
-> Liquid particles are packed less closely with each other as compared to solid particles in a disorderly manner. They move around in a random motion; sliding past each other.

The methane molecule undergoes oxidation and the carbon is oxidized to carbon dioxide and hydrogen to water.
In this reaction there is cleavage of four C-H bonds and two O=O bonds
there will be formation of two C=O bonds and four O-H bonds.
Overall due to more bond cleavage energy there will be evolution of energy. thus combustion is an exothermic reaction.
