Want this question answered?
347 J/g.K or 83 cal are released.
Delta G (written triangle G) = Delta H -T Delta S
i wanna know this answer too.
this is energy released
Exothermic Reactions: The delta h is always NEGATIVE! Energy is released (delta is the little triangle in front of the H)
Grams liquid × mol/g × Hfusion
Grams Liquid x mol/g x Hfusion
Energy is released.
grams liquid x mol/g x H fusion
The mol is involved in many chemical calculations. And the molar mass mass is calculated from the chemical formula.
Grams liquid × mol/g × Hfusion
347 J/g.K or 83 cal are released.
Released. It is called the Heat of Fusion. It is absorbed when turning from solid to liquid, and released when turning from liquid to solid.

You need to get the energy OUT of the water; otherwise it won't freeze. This is usually done by putting the water in contact with something colder.

When the molar enthalpy of fusion for water is 6.008 kJ/mol, there is 84.4 kJ released when 253 grams of liquid water freezes. 84.4 kJ
