Answer: The enthalpy change is 34.3 kJ
Explanation:
The conversions involved in this process are :
Now we have to calculate the enthalpy change.
where,
= enthalpy change = ?
m = mass of water = 72.0 g
= specific heat of ice =
= specific heat of liquid water =
n = number of moles of water =
= enthalpy change for fusion = 6010 J/mole
Now put all the given values in the above expression, we get
(1 KJ = 1000 J)
Therefore, the enthalpy change is 34.3 kJ
