Question
Aluminium is a solid at room temperature.Which one of the following explains why aluminium is a solid at room temperature?It has a high boiling & melting point.It is malleable.It has a high density.It is ductile.
Solution
The reason why aluminium is a solid at room temperature is because it has a high boiling and melting point.
Here's a step-by-step explanation:
-
The state of a substance (solid, liquid, or gas) at a given temperature depends on the strength of the forces between its particles.
-
In metals like aluminium, these forces are in the form of metallic bonds, which are very strong.
-
These strong bonds mean that a lot of energy (in the form of heat) is needed to break them and turn the metal from a solid into a liquid or gas.
-
The temperature at which this happens is called the melting point (for the transition from solid to liquid) or the boiling point (for the transition from liquid to gas).
-
Aluminium has a high melting point (over 660 degrees Celsius) and a high boiling point (over 200
