Different substances have different melting points, depending on the strength of the intermolecular forces between their particles. Substances with weaker intermolecular forces typically have lower melting points, while those with stronger forces have higher melting points.

The melting point of a solid is the minimum temperature at which it melts and transitions into a liquid state at atmospheric pressure. It serves as a characteristic property of the substance and can be used for identification and characterization ...
As the temperature rises and the kinetic energy of solid particles increases, the energy supplied by heat overcomes the forces of attraction between the particles. Eventually, the particles break free from their fixed positions and begin to move more freely, ...
When the temperature of a solid is increased, the kinetic energy of its particles also increases. This causes the particles to vibrate with greater speed within their fixed positions.
Increasing the temperature of a gas increases the kinetic energy of its particles, causing them to move faster. With higher speeds, gas particles collide more frequently and with greater force, resulting in an increase in the pressure exerted by the ...
