What change of state is liquid to solid?
Naomi AronsonLiquid to solid phase transitions are classified under first order phase transitions.
Ehrenfest classified phase transitions among first or second order depending on the order of derivatives of the Gibb's function that undergoes discontinuous changes at the phase boundary.
In the solid-liquid phase transition, there is a discontinuous change of molar entropy and molar volume of the system which are first derivatives of the molar Gibbs' function hence classifying it as a first order phase transition.
It may be noted that first order phase transitions have latent heat associated with them.
As you may be familiar there is a latent heat associated with the melting of ice or freezing of water. Therefore, fusion (or it's reverse process freezing) are first order phase transitions.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- The value of #DeltaH_(vap)# of substance X is 45.7 kJ/mol and its normal boiling point is 72.5 degrees C. How do you calculate #DeltaS_(vap)#, #DeltaS_(surr)# and #DeltaG_(vap)# for the vaporization of one mole of this substance at 72.5°C and 1 atm?
- Snow and Ice are both solid forms of water,then why doesn't snow have such a solid structure as ice and why do their colors differ? Even sometimes we see snowy white color in some parts of an ice cube,but snow doesn't appear transparent from anywhere.why?
