There is Kinetic energy involved in the state something is in. The molecules in a liquid are moving around quicker than those in a solid.
That's one reason.
The ice requires energy to melt. Bonds must be broken to get from a solid to a liquid.

A single replacement or displacement reaction occurs when one ingredient in a compound replaces another. Only another metal can replace a less active one; a metal can only displace another metal, and a non-metal can only displace another non-metal.
<h3>Displacement reaction:</h3>
The tendency of the element to lose electrons is what makes it metallic. Due to their bigger sizes and propensity to lose electrons as size, the number of shells, and nuclear force of attraction rise, the most active metals are found on the left side of the periodic table.
The reaction in which the more reactive element displaces the less reactive element is known as the displacement reaction.
When we combine an active metal with HCl, the reaction is as follows:
We are taking sodium, Na which is the most active metal. It will replace H in HCl because it is more reactive than H.
2Na + 2HCl → 2NaCl + H₂
Three ways to recognize if a single displacement reaction has taken place:
1. Color change
2. Formation of bubbles (a gas)
3. Formation of a precipitate
