Hot metals cool down in water because the water absorbs the heat energy, until both the metal and the water are the same temperature (thermodynamic equilibrium).
Water cools more effectively than air for two reasons. One is that the greater number of molecules in a volume of water can take more heat energy than the fewer molecules in air. The second is that water will change phase (boil away, evaporate) at temperatures over 100° C, removing even more heat from the system.

Does saltwater make metal rust faster than unsalted water?
Salt water does make nails rust faster than non-salted water, because when salt is added to water, it will rust the top layer of the nail, and then make the nail basically shed its top layer. Then the salt will rust that layer, and this process continues until the whole nail is rusted. Normal water can only really rust the top layer, and can't get to the rest of the nail.
What two substances are need to rust Iron?
ANSWER:oxygen and water
What happens to iron placed in a test tube with a stopper?
Iron and oxygen in a test tube alone will not react (observed by placing a piece of iron in a test tube with a stopper).Iron and water in a test tube alone will not react (observed by completely submerging a piece of iron in water in a test tube with a stopper).Iron, water and oxygen in a test tube will react (observed by placing a piece of iron in a test tube and submerging half of it with water). The following reaction will take place: iron + water + oxygen ----> hydrated iron(III) oxide. Hydrated iron(III) oxide is the chemical name for rust, which will appear as orange flaking on the piece of iron. To speed up this reaction you can use a bit of salt as a catalyst.
What water makes iron rust faster?
Salt water.
Does an iron nail rust faster in salt or tap water?
An iron nail will rust faster in saltwater than in tap water. This is because saltwater is conductive and accelerates the rusting process by promoting the flow of electrons between the iron nail and oxygen in the water.
Does sound go faster through water or iron?
Sound travels faster in iron. Usually sound travels faster in media with higher density. Also presence of lattice makes difference too.
Why is rusting of iron faster in rainy days?
rusting of iron is faster in rainy days because water is responsible for the rusting of iron i.e the presence of oxygen
Why does iron rust faster in salt water than in tap water?
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.
What added factors can cause iron to rust faster?
water
Which warms up faster when heat is applied iron water sand or wood?
Iron has the lowest specific heat, so it will heat up faster.
How does an iron cool down?
An iron cools down by losing heat energy to its surroundings through conduction, convection, and radiation. As the iron's temperature decreases, the molecules inside the iron slow down, resulting in a reduction of its thermal energy.
What liquid causes an iron nail to rust faster water or coke?
coke will make it rust faster
When you are through using a soldering iron does cool it with water?
NO....it cools by itself.
Will iron rust faster in salt water or fresh water?
Iron will rust more quickly in salt water than fresh freshwater. The salt in the water accelerates the corrosion process.
Which liquids rust faster?
Liquids do not rust, iron does, rust is Hydrated Iron (III) oxide, so the only substance which can rust iron is water
