Explain Enthalpy of neutralisation.

Define standard enthalpy of fusion or molar enthaply of fusion (Delta_(fus) H^("ϴ")) .

DeltaS for freezing of 10 g of H_(2)O(l) (enthalpy of fusion is 80 cal/g) at 0^(@)C and 1 atm is :

Can enthalpy of combustion be positive ?

Define enthalpy of solution.

Explain nuclear fusion. What are the conditions for fusion?

Molal depression constant is calculated from the enthalpy of fusion (DeltaH_(f)) and b.pt. of solvent using the relation.
