Activity 2. Answer the following questions a. How long does it take an iron nail exposed to the rain to rust?______________________________________________________________________________ b. Compare the rusting of iron to how fast milk curdles when an acid like vinegar or calamansi juice is added to it.

Why do we keep food in the refrigerator? ______________________________________________________________________________ e. How do particles move at high temperatures compared at low temperatures?
Science behind corrosion-test
Corrosion is defined as an activity that transforms refined metals into more chemically stable forms such as oxide, hydroxide, carbonate, or sulfide. It refers to the slow decomposition of things (typically metals); thanks to chemical and/or electrochemical reactions with their surroundings. Corrosion engineering is the science of preventing and controlling corrosion.
