You are watching: Are freezing and melting point the same
Melting - solid come liquid once a heavy is heated, its particles get enough energy to get over the bonding pressures holding them firmly in place. They start to relocate about, but stay close to their neighbouring particles, rolling approximately each other. This bit movement allows the substance to circulation and kind a liquid. Solids and liquids are comparable in your density, the is, number of particles every unit volume. Lock differ only in the capability of the fluid to circulation and adjust shape to accounting the shape of the bottom component 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 corpuscle in the solid, and also the more powerful the bonding, the higher the melt point.
Helium, the lightest and weakest bonded substance known, has a melting point really near pure zero, or - 273°C. In ~ the other end of the scale, Tungsten, make of lot heavier particles v very solid bonding, melts at 3410°C.
