Question

I will thumbs up if correct !

On a hot day (or during a stressful exam!), your body produces liquid sweat
which then evaporates according to the equation:
H2O(1) → H20(g)
AH = +44 kJ/mol
Is this process a chemical or a physical change?
Is this process endothermic or exothermic? Why?
O Endothermic; liquid-liquid IMFS are more stable than gas-gas IMFS.
O Exothermic; liquid-liquid IMFS are more stable than gas-gas IMFS.
Endothermic; gases can be arranged in more ways than liquids.
O Exothermic; gases can be arranged in more ways than liquids.
