Question

how should the baking of a pizza be categorized?
as an exothermic process because the dough releases heat
as an endothermic process because the dough releases heat
as an exothermic process because the dough absorbs heat
as an endothermic process because the dough absorbs heat

Explanation:

To solve this, we recall: Endothermic processes absorb heat (system takes in heat from surroundings), exothermic release heat (system gives off heat to surroundings). Baking pizza: dough (system) absorbs heat from oven (surroundings) to cook. So it's endothermic (absorbs heat). Now check options:

• 1st: Exothermic (releases) → wrong.
• 2nd: Endothermic but says "releases" → wrong.
• 3rd: Exothermic but says "absorbs" → wrong.
• 4th: Endothermic (absorbs) → correct.

Answer:

D. as an endothermic process because the dough absorbs heat (assuming the options are labeled A, B, C, D in order; if original labels differ, adjust, but based on the order: the fourth option "as an endothermic process because the dough absorbs heat")
