Melting point of any solid depends on pressure as `(P_(2)-P_(1))=(DeltaH_("fusion"))/(Vl-V_(s))ln"(T_(2))/(T_(1))`
Calculate freezing point of water `("in" ^(@)C)` at a pressure of `1001` bar if freezing point of water at 1 bar is `0^(@)C.` Molar volume of ice and liquid water is `19.65` ml and 18 ml respectively and increase in enthalpy due to melting is `6600"J"//"mole"`
`[In0.975=-0.025]`
Instruction: Neglect sign of the temperature, therefore if your answer is `-8.65^(@) C`,express answer as 9]

Answer

7
