It matters to the aerodynamics of it because sometimes it's good to have the weight but only if it can take it.

Answer:
The answer is C) The temperature at which the solid-state turns into liquid
Explanation:
The melting point of a substance is the temperature at which it shifts state from solid to liquid. At the melting point, the solid and liquid levels exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached. More heat then will convert the solid into a liquid with no temperature change. This occurs when the internal energy of the solid increases, commonly by the application of heat or pressure, which increases the substance's temperature to the melting point.
The amount of molecules assembled, the processes performed on the substances. I'm not exactly sure of the question to be honest, but there's a start
