Question
hello sir,
my name is danny, age-21, doing mechanical engineering. my question is what is the effect of pressure on freezing point of water ??? the boiling point although increases with increase in pressure, like at 1-atm boiling point is 100 degree C, at lower pressure around 0.5-atm it can be 90 degree C and at higher pressure 2-atm boiling point would be 110 degree C. how freezing point gets affected with increase or decrease of pressure ??? please explain with example like i did in case of boiling point.
!!  thank you  !!

It's easy for pressure to affect the boiling point since b.p. is defined as the temperature at which the vapor pressure of the liquid equals the pressure of the gas above it.  Since water is nearly incompressible, pressure has almost no effect on the freezing point.
