You are watching: What is the difference between melting point and freezing point
Melting - solid to liquid as soon as a hard is heated, that is particles gain enough energy to overcome the bonding forces holding them steady in place. They begin to move about, yet stay close come their adjoining particles, rolling around each other. This bit movement enables the problem to flow and kind a liquid. Solids and also liquids are similar in your density, the is, variety of particles every unit volume. They differ just in the capability of the fluid to flow and change shape to occupy the form of the bottom part of the container.

Melting point out various solids have different melting points depending upon the stamin of bonding between the particles and the fixed of the particles. Essentially, the more heavier the particles in the solid, and the stronger the bonding, the greater the melt point.
Helium, the lightest and weakest bonded substance known, has actually a melting point very near absolute zero, or - 273°C. In ~ the other end of the scale, Tungsten, do of much heavier particles v very strong bonding, melts at 3410°C.
