What is the entropy change of a 0.349 g spoonful of water that evaporates completely on a hot plate whose temperature is slightly above the boiling point of water?

Explanation:

As we know that entropy change for phase conversion is given as

Here we know that heat required to change the phase of the water is given as

here we have

L = 2250000 J/kg

now we have

also we know that temperature is approximately same as boiling temperature

so we have

so here we have
