Question

how much energy is transferred when 1 gm of boiling water at 100 degree celcius condenses to water at 100 degree celcius?

Answer 1

22.5 x 10 to the power 5 kilo/joules energy is transferred when boiling water at 100 degree celcius condenses to water at 100 degree celcius

Answer 2

The latent heat of vaporization for water is 2257 KJ per Kg . I'm pretty sure that's exactly the same as 2257 joules per gram. So ... When 1 gm of STEAM at 100 C condenses to 1 gm of liquid water at 100 C, it releases 2257 joules of heat energy to its environment.
