Aluminum is in a solid state at room temperature.
At room temperature, which is typically around 20 to 25 degrees Celsius (68 to 77 degrees Fahrenheit), aluminum maintains its solid form. This is due to its atomic structure and the bonding between its atoms, which hold them tightly together in a fixed arrangement. Unlike gases or liquids, solids have a definite shape and volume, and aluminum exemplifies this characteristic. Moreover, aluminum has a relatively high melting point of about 660 degrees Celsius (1220 degrees Fahrenheit), which means it remains solid under standard room conditions. This solid state is what allows aluminum to be used widely in construction, transportation, and various products due to its strength, lightweight nature, and resistance to corrosion.
