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.

∙ 14y agoThe molecules are much closer together is solids than in water. When the molecules are closer together then the material conducts better.
When there is movement of the particles that make up the material; they don't have to move as far to bump the next particle. This speeds up the movement process...sort of like having a line of people passing a bucket of water instead of one or two people running with the buckets.
Extra: did you know that the freezing point of any solid is the point at which it becomes a solid ? So, the feezing point of iron is...? Really high !

∙ 14y agoThe molecules of metals are closely packed together, which transfers heat better than air, which is spaced apart. (this only answers why it feels colder if they are at the same temprature)
Be careful with your wording, because "cold" refers to temperature. It is not hard to conceive of a situation where the metal is at 100C, and air is at 0C.

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
How are the density of wood and iron the same?
iron is more dense then water and wood is less dense then water. iron sinks because it is heavier then the density of water. wood sinks because woods density is lighter then the density of water.
What cools liquid faster glass or shiny metal?
Metal is a better conductor than glass and the heat will conduct out better, hence, water will cool down faster in metal container. Thermal conductivity for glass is approx. 1 W/m.K For Metal Aluminum 204 W/m.K Iron (pure) 73 W/m.K Nickel Chromium (80%:20%) 12 W/m.K
Why does iron rust faster in salt water than in tap water?
Salt water contains Na+ & Cl- ions which are highly reactive with iron to form FeCl2 .So iron rust faster in salt water.
Does an iron nail rust faster in salt or tap water?
It rusts faster in salt water.
What water makes iron rust faster?
Salt water.
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
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.
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.
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.
What conditions will make iron and steel rust?
Rusting occur in iron when it reacts with oxygen and water...the less salts in the water the faster the rusting occurs...and the more percentage of oxygen the faster it rusts.
What is the densities of iron filings table salt pepper in water salt and iron filings and sugar in water?
angela and ev jackson are cool
