When 16.4 g of steam at 100°c condenses how much heat is released?

37064 J

Explanation:

Data Given:

mass of Steam (m) = 16.4 g

heat released (Q) = ?

Solution:

This question is related to the latent heat of condensation.

Latent heat of condensation is the amount of heat released when water vapors condenses to liquid.

Formula used

            Q = m x Lc . . . . . (1)

where

Lc = specific latent heat of condensation

Latent heat of  vaporization of water is exactly equal to heat of condensation with - charge

So, Latent heat of  vaporization of water have a constant value

Latent heat of  vaporization of water = 2260 J/g

So

Latent heat of condensation of water will be = - 2260 J/g

Put values in eq. 1

          Q = (16.4 g) x (- 2260 J/g)

          Q = - 37064 J

So,  37064 J of heat will be released negative sign indicate release of energy

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
