High melting points

High melting points occur when the particles in a substance are held together strongly, requiring a significant amount of heat energy to break those bonds and change from solid to liquid. For example, metals like tungsten have high melting points because their atoms are tightly packed and strongly bonded, needing more heat to break those bonds. Conversely, substances with weaker bonds melt at lower temperatures. This property helps explain why some materials are used in high-temperature environments, as they remain solid even when exposed to intense heat.
