Answer:
[tex]\Delta S = 2.11 J/K[/tex]
Explanation:
As we know that entropy change for phase conversion is given as
[tex]\Delta S = \frac{\Delta Q}{T}[/tex]
Here we know that heat required to change the phase of the water is given as
[tex]\Delta Q = mL[/tex]
here we have
[tex]m = 0.349 g = 3.49\times 10^{-4} kg[/tex]
L = 2250000 J/kg
now we have
[tex]\Delta Q = (3.49 \times 10^{-4})\times 2250000[/tex]
[tex]\Delta Q = 788.9 J[/tex]
also we know that temperature is approximately same as boiling temperature
so we have
[tex]T = 373 k[/tex]
so here we have
[tex]\Delta S = \frac{788.9}{373}[/tex]
[tex]\Delta S = 2.11 J/K[/tex]
