Determine whether each of the following is exothermic or endothermic and indicate the sign of δh. A. Natural gas burning on a stove b. Isopropyl alcohol evaporating from skin c. Water condensing from steam

A) exothermic, δh is negative

B) endothermic, δh is positive

C) endothermic, δh is positive

Explanation:

And endothermic process absorbs heat from its sorrounding, cooling the sorrounding down. Whereas an exothermic process releases heat to its sorrounding raising the temperature of the sorrounding system.
