Question

Show the calculation of the energy involved in condensation of 150 grams of steam at 100oC if the Heat of Vaporization for water is 2.26 kJ/g.

Answer 1

Answer : The energy involved in condensation is, 339 kJ

Explanation :

Formula used :

$q=m\times L$

where,

q = heat required = ?

L = latent heat of vaporization of water = $2.26kJ/g$

m = mass of water = 150 g

Now put all the given values in the above formula, we get:

$q=(150g)\times (2.26kJ/g)$

$q=339kJ$

Therefore, the energy involved in condensation is, 339 kJ
