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* 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)* (2.26kJ/g)`

`q=339kJ`

Therefore, the energy involved in condensation is, 339 kJ
