Melting Point

Imagine trying to remove a stubborn, stuck jar lid that won't budge no matter how hard you twist. Just like how applying the right amount of heat can loosen the lid, reaching the melting point provides the energy needed for a solid's rigid structure to weaken and flow into a liquid state. In both scenarios, a threshold is met—twisting force for the jar and temperature for the solid—allowing for a transition from a fixed, unyielding state to a more flexible one.

Melting Point: The temperature at which a solid changes into a liquid is called the melting point. The melting point is when a solid gets warm enough to turn into a liquid.
