Which of the following substances will not get rusted easily? |
Ship submerged in water Iron rod exposed to moisture Stainless steel All of these |
Stainless steel |
The correct answer is option 3. Stainless steel. Stainless steel will not get rusted easily. Stainless steel is an alloy of iron that contains chromium, which forms a thin, protective oxide layer on the surface. This layer inhibits the formation of rust (iron oxide), providing stainless steel with corrosion resistance. A ship submerged in water is likely to be made of materials resistant to rust, such as stainless steel or other corrosion-resistant alloys. An iron rod exposed to moisture is prone to rusting over time, as moisture and oxygen can react with iron to form iron oxide (rust). |
