Answer:
The correct answer is - 2.26*10^5 J
Explanation:
Given:
The amount of water need to vaporized = 100 g
We know:
The heat of vaporization of water = 2260 j/g
The required heat (q)
= mass of the liquid (m) * the heat of vaporization of liquid (ΔH)
q = m*ΔH .......1
So, from the equation 1,
the 100 gram sample of water being completely vaporized needs
= 2260*100
=2.26*10^5 J.
Thus, the correct answer is = 2.26*10^5 J.
