Mercury Hg -38.8' Now you could consider Hydrogen to be a metal if you are willing to get creative with the definition of metal. In that case it would be −259.16 °C
The lowest freezing point is observed for 1 mole of KOH, because its one moles produce 2 moles of ions in solution, 1 mole of cation K+ and 1 mole of anion OH-.
That really depends what you mean by grit. If it's just powdered rock, there is no effect. If you mean rock salt, then the freezing point is reduced because the salt dissolves. The lowest freezing point achievable for salt solution is - 21.1 degrees C.
what is the freezing point of N2O
it is increased with the increasing density

This occurs because the refrigerant must be capable of releasing excess heat easily. It can do this by boiling and having it in steam.
Helium melting point: -272,2 0C Rhenium boiling point: 5 596 0C
you can turn the graphics all down to the lowest point which stops it from freezing.

(NH4)2SO4 vs Ce(NO3)4. Ammonium sulfate gives 3 ions in solution whereas cerium nitrate will give 5 ions in solution. So Ce(NO3)4 will have lowest freezing point.
Freezes the fastest can be of 2 mean. For liquid to reach the freezing point first, the liquid with higher molecular mass or stronger intermolecular force would have higher freezing point and can be considered freezing faster. But it might took quite a while to freeze at the freezing point. For liquid to become solid with the least energy transfer required. The liquid with the lowest intermolecular force would change the state faster at freezing point. But the freezing point might be extremely low.
