# Question #24009

##### 1 Answer

128820 J, due to latent heat of vaporization. Note that the answer may be slightly different if your textbook uses a different value for

#### Explanation:

When liquid water changes temperature, the amount of energy needed to change that temperature is the Specific Heat Capacity *latent heat of vaprozation.*

The latent heat of vaporization for water is

So if we have 57g of water already at 100C, then the heat needed is given by:

I have seen different values of

If the water started below 100C, we would need to calculate that energy as well, using the specific heat capacity (
