Oil, a complex mixture of hydrocarbons, takes millions of years to form naturally. Iron is a naturally occurring element, formed by fusion in the core of a star.
As far as humans need be concerned, iron is always present and oil is formed. If you must have one faster than the other, iron is formed faster than oil.
Salt water is a more conductive solution than tap water, which accelerates the electrochemical process of iron oxidation (rusting). The chloride ions in salt water can also react with the iron to form more rust at a faster rate compared to tap water.
No, oil is being used faster than it is being replaced. Oil is a non-renewable resource that takes millions of years to form, while current consumption rates are depleting known reserves at a much faster rate.
Nails are made of iron, but pennies are copper and zinc. Iron reacts with oxygen to form rust, but copper on the outside of a penny does not.
iron rusts faster in presence of moisture and air.
Oil.
Iron
Iron will float in oil in most cases. However, for iron to float in oil, it must have a density which is lower than the oil.
iron
rusting of iron is faster in rainy days because water is responsible for the rusting of iron i.e the presence of oxygen
Zinc typically reacts faster than iron in many chemical reactions due to its higher reactivity and position in the reactivity series. Zinc readily loses electrons to form positive ions, while iron tends to react more slowly due to its lower reactivity.
soda because it is the most acidic
Iron typically heats up faster than glass because iron has higher thermal conductivity. This means that heat transfers more quickly through iron than through glass, allowing iron to reach higher temperatures faster. Glass, on the other hand, has lower thermal conductivity and heats up more slowly.
