Increasing the temperature up to the melting point.
if you were to constantly increase the temperature of a solid you would eventually reach the melting point for that particular substance, at which time the solid would melt to a liquid. if you were to keep heating the substance, at some point the liquid would reach its boiling point and would evaporate to a gas.
Putting a substance under pressure increases its melting point because substances expand as they melt. Putting them under pressure makes it harder for them to expand, which means that they require more energy (heat) in order to transition from a solid state to a liquid state. If a substance is under pressure, decreasing the pressure will lower its melting point.
The lower the amount of substance, the faster it reaches the boiling point. The more the amount of substance, the longer it takes to reach the boiling point. Hope that this is what you wanted to know! :)
A solid becomes a liquid when it temperature has reached its Melting Point (also called it Point of Fusion.)
You simply subtract the melting point of steel, minus the ambient temperature.
Each substance has a specific melting point (excepting cases of sublimation or thermal degradation).

the solid must reach its melting point which varies with every substance

you must reach its melting point or freezing point or boiling point.

Heating curves (temp vs time) show the transition of a solid to a liquid to a gas. The solid begins to absorb heat, which is represented by a gradual increase in your curve starting from the origin. Eventually, the solid will reach the melting point, at which the temperature will cease to increase until it has fully transitioned to a liquid phase. Therefore, the melting point is the y-value correspondind to the first horizontal portion of the heating curve.
Nothing freezes "faster", they need different temperatures to freeze: even if you keep water at 2 degrees celsius for months, it won't freeze! However, since the melting point is the same as the freezing point, I'd have to say the answer to which freezes more easily is water since it contains no solutes which are considered impurities. Impurities lower the melting point of a substance, and therefore lower its freezing point, making it more difficult to reach the freezing point of Orange Juice than it is to reach the freezing point of water.
