Melting need an increase of the temperature.
Drop the temperature.
An endothermic reaction usually exhibits a drop in temperature.
No, it is a highly viscous liquid, do a search on the Pitch Drop Experiment.
The melting point of a substance is the temperature at which solid state of a substance co exist in equilibrium with its liquid state. It is also called the freezing point (melting is the same process as freezing, just in the opposite direction, and so the temperature is identical).See Web LinksSee the Web Links for "Answers.com: Melting point" below for more information.The melting point is a point where a solid begins to heat and lose mass. It generally changes from a solid state to a liquid state.
In relation to grease, the drop point is the temperature at which the grease changes from a solid to a semi-solid state. This is an important characteristic as it signifies the high-temperature stability and performance of the grease.
When a liquid is cooled, its temperature decreases until it begins to freeze. At this point the temperature stops decreasing, because the energy being removed comes from the phase change from liquid to solid and not from changes in the temperature. Once it is completely frozen, the temperature will begin to drop again.Note that this is only true for pure substances like water. Other substances often freeze over a range of temperatures instead of at a single "freezing point". The freezing of these substances is more complicated.
To determine which change of state took place, observe the temperature and pressure conditions of the substance. For example, if a solid melts into a liquid, the temperature will rise as heat is applied, while the solid maintains its shape until it is fully melted. Conversely, if a liquid freezes into a solid, the temperature will drop as heat is removed, and the liquid will solidify into a fixed shape. Additionally, changes in volume and the appearance of bubbles or vapor can indicate transitions like evaporation or condensation.
water changes from a liquid to a solid when you drop it below 32 F or 0 C. It also evaporates, changing into a gas in warmer weather.

When water is boiled, it turns into vapor or steam as it reaches a high temperature. As the steam cools down, it condenses back into liquid water. If the temperature continues to drop, the liquid water freezes and turns into solid ice. This transition from boiling water to freezing air involves changes in temperature and state of matter.
If cubes of solid argon were placed in a cup of liquid argon, the solid argon would begin to melt due to the heat transfer from the warmer liquid argon. As the solid argon melts, it would turn into liquid argon, contributing to the overall volume of the liquid. Since both the solid and liquid argon are composed of the same substance, the process would not result in any significant chemical reactions or changes in the properties of argon. The temperature of the liquid may drop slightly as it absorbs heat to melt the solid, but it would remain within the liquid argon's boiling point range.
Assuming you put a bowl of ice cubes into the fridge (which is well isolated, but the temperatue is above freezing level). The ice will begin to melt. Even if you turn the fridge off, the temperature in the fridge will drop as the ice takes up energy from the surrounding air to liquify. The answer is: Yes.
