Melting point of aluminium: 660.32 0C Boiling point of aluminium: 2519 0C
The melting point of sodium chloride is 801 0C. The melting point of aluminium oxide is 2 072 0C.
The melting point for potassium is 63.38 °C.
Boiling point 774°C Melting point 63.65°C
The boiling point is always higher than the melting point.

The melting point of sodium chloride is 801 0C. The melting point of aluminium oxide is 2 072 0C.
The melting point is 1220.58F. The boiling point is 4566F.
It requires much more energy to convert the liquid potassium into a vapor than it does to convert the solid to a liquid.
Calcium at 860 degrees celsius potassium melts at a mere 65 degrees celsius
The melting point of aluminium is 660,32 0C.
The melting point for potassium is 63.38 °C.
KF has small size than KCl. So the packing of atoms / ions in KF is more than that in KCl. So a larger energy is needed to separate the atoms from solid state to liquid state and hence KF has higher melting point than KCl.

CaO has a higher melting point.
Argon has the higher melting point.
