In the presence of oxygen - rusting; but now many types of stainless steels are known.
No, steel is not lighter when in water. Steel is denser than water, so it will sink in water rather than float. The weight of the steel displaces an amount of water equal to its weight, making it sink.
No, 7.81 g of steel will sink in water because steel is denser than water. Steel has a higher density than water, so it will not displace enough water to float.
It stops the steel from rusting by not letting oxygen or water touch the steel, as oxygen and water need to present for steel to rust.
No, steel is denser than saline water, so a steel pin would sink in saline water.
That really depends on the temperature of the water and the steel !
No, titanium steel does not rust when exposed to water.
No, a solid steel bar will sink in water because steel is denser than water. Only objects with a lower density than water will float.
Salt water will rust steel faster than fresh water or refrigerated water. This is due to the corrosive properties of salt, which accelerates the oxidation process that leads to rust formation on steel surfaces.
A steel cube sinks in water because steel is denser than water, meaning it displaces less water when submerged. The weight of the steel cube is greater than the buoyant force acting on it, causing it to sink.
Well when you put steel in water, the water will make the steel more softened, and then the rust starts forming cause the water dissolves the steel atoms then you have a red rusted steel metals.
Steel wool does not get softer under water. That is just your perception.
A needle is made of steel ; as steel is denser than water, a steel needle should sink in water because of this.
