Rust and Corrosion of Metals

20 questions

Question 1: Yellow rust forms on metals that are exposed to large amounts of water.

A. Ano

B. Ne

Explanation: Yellow rust forms on metals that are exposed to large amounts of water, as seen near sinks or bathtubs where there is a constant drip.

Question 2: Rust improves the electrical conductivity of metals.

A. Ano

B. Ne

Explanation: Rust acts as an insulator, which hinders the electrical conductivity of metals, rather than improving it.

Question 3: In the process of galvanising, the thin layer of zinc coated onto iron or steel flakes off with the same ease as oxidised iron.

A. Ano

B. Ne

Explanation: The study materials indicate that when iron or steel is galvanised with zinc, the zinc also oxidises, but it 'doesn't flake off as easily as iron oxidises'.

Question 4: Rust enhances the ability of metal columns to support a house's weight.

A. Ano

B. Ne

Explanation: Rust weakens support structures, making columns supporting a house unable to support as much weight as they should.

Question 5: Rust forms when iron reacts with oxygen to create iron oxide.

A. Ano

B. Ne

Explanation: The study materials explain the formation of rust with the chemical equation: 'Iron + Oxygen → Iron Oxide'. This indicates that iron reacts with oxygen to form iron oxide, which is rust.
