Given that the melting point of water at 218 atm is 1.61 Celcius degree,and at 1 atm,the melting point is 0 celcius degree.[:)][:)]
what is the melting point of water at 0.5 atm?can anyone show the calculation step by step?[:D][:D]

---------------
Melting point at 1 ATM is 0
melting point at 218 ATM is 1.61
What is it at 0.5ATM? What is it at 50,662.5pa?
1 = 0 . 218 = 1.61 if there is a relationship then
1.61 / 218 = 0.007385'C
a 0.007385'C per ATM unit.
0.007385 / 2 = 0.003693'C shift for each 50,662.5pa
So at 0.5ATM Water might melt at minus 0.003693'C "degrees Celius"
