What is the difference between melting and burning a substance? one mass conserved in another process?

The word "Melting" is directly related to liquefying something, such as when you melt ice. Burning something is essentially heating it up to the point that it turns into a gas then the gas becomes fire. Melting conserves the mass but in a different form. Burning converts the substance into a different form but then immediately consumes it. Hope this helps!

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
