Question

name
exothermic and endothermic – practice
instructions: identify which objects are undergoing exothermic and endothermic processes.
an egg is cracked open and cooked in a hot pan

1. which object is undergoing an endothermic process?
2. which object is undergoing an exothermic process?

a heated screw is placed into a cup of cold water

Explanation:

1)

An endothermic process absorbs heat. The egg is cooked in a hot pan, so it absorbs heat from the pan to cook, undergoing an endothermic process.

An exothermic process releases heat. The hot pan (when cooking the egg) releases heat to the egg, and the heated screw releases heat to the cold water. For the first scenario, the hot pan; for the second, the heated screw. But in the first part (egg cooking), the pan is exothermic. In the screw - water scenario, the screw is exothermic.

Answer:

The egg
