Tm (Melting Temperature)

Tm, or Melting Temperature, is the temperature at which a solid becomes a liquid. When a substance, like ice, is heated to its Tm, the molecules gain enough energy to break free from their fixed positions, resulting in a phase change from solid to liquid. Each material has a unique Tm, which is important in various fields, including chemistry and materials science. Understanding Tm helps in processes like recycling, cooking, and the production of materials, ensuring they behave as expected at different temperatures.
