Answer:

211.9 J

Step-by-step explanation:

The molecules of water release heat during the transition of water vapor to liquid water, but the temperature of the water does not change with it.

The amount of heat released can be represented by the formula:


Q=mL_e

where
Q = heat energy,
m = mass of water and
L = latent heat of evaporation.

The latent heat of evaporation for water is
L=2257 kJ/kg and the mass of the water is
m=93.9 g=0.0939 kg.

The amount of heat released in this process is:


Q=mL_e = (0.0939kg)(2257 kJ/kg)= 211.9 J
