Melting Point: The melting point of water is 0°C (273K), and its boiling point is 100°C (373K) at 1 atmosphere pressure. Room temperature is typically around 25°C, which is well within the liquid phase range of water (between its melting and boiling points).
Molecular Motion: At room temperature, the kinetic energy of water molecules is sufficient for them to move around and slide past one another, but not enough to break the intermolecular bonds completely (as in a gas) or keep them in a rigid, fixed position (as in a solid). This allows water to exist in the liquid state.
Melting Point: Iron has a very high melting point of 1538°C (1811K). Since room temperature is only around 25°C, which is much lower than iron’s melting point, the iron almirah remains in the solid state.
Strong Atomic Bonds: In iron, the atoms are tightly packed and held together by strong metallic bonds, which require a large amount of energy to break. This strong bonding keeps the iron in the solid state at temperatures well below its melting point.
These two reasons explain why water remains a liquid at room temperature and why an iron almirah stays solid at the same temperature.
