Given:

For the change:

space space space space space space straight H subscript 2 straight O subscript left parenthesis straight l right parenthesis space end subscript space space rightwards arrow with straight H subscript 1 on top space space straight H subscript 2 straight O subscript open parentheses straight l close parentheses end subscript space space space space rightwards arrow with straight H subscript 2 on top space space space space straight H subscript 2 straight O subscript left parenthesis straight g right parenthesis end subscript space left parenthesis 100 space degree straight C right parenthesis space space space space space space space space space open parentheses space 0 space degree straight C close parentheses space space space space space space space space space space space space space space open parentheses space 0 space degree straight C close parentheses space space space space space space

ΔH = H₁+ H₂

n = 1 mole

T = 100 °C

H₁ = nCdT

= 1× (-4.2)×18×100

= -7560 J/mol

= -7.56 kJ/mol

H₂ = -6 kJ/mol

ΔH = -7.56 + (-6)

ΔH = -13.56 kJ/mol

In the process the volume change is negligible

Therefore, ΔH = ΔU +PΔV

ΔV =0

Change in internal energy = -13.56 kJ/mol
