Rust Task

Fast Rust Task
What 3 ingredients are needed for rust to occur.
Oxygen from the air
Write a brief paragraph explaining the rusting process (why rusting occurs)
Rusting occurs when the oxygen in the air and water mixes together, when it touches iron, the iron reacts and this form is called Iron Oxide. When the water and iron oxide contact each other, they form a new red substance called rust. As the rust forms over time, they could actually disintegrate.
How could you prevent something from rusting?
Keep iron in an isolated dry area and make sure that no water or air comes in, that way it can’t form something that is rusting. Another way to prevent rusting is by painting the metal/iron, coating it 4 times would be ideal since it does keep air and moisture from the atmosphere from interacting with each other.
Write 3 sentences explaining something new you’ve learned from this reading.
  • I have found out that the rust that you usually find everywhere is actually the fourth most common element that is found in the Earth’s crust, the rust makes up to 5% of the Earth’s crust.
  • The Auckland harbor bridge uses about 3 tonnes of paint coating to stop about 6000 tonnes of steel from rusting. They repaint it every 4 years so it doesn’t rust.
  • Whenever oxygen mixes with water on something on iron, it usually takes several months to form rust.
