What materials transfer electrical current?
All metals, and certain other materials such as carbon and salt water.
How does the presence of salt in water affect the upthrust of the water on a ship?
Salt makes the water denser or heavier if you like. the result is that anything including ships will float more easily.
What are three factors that affect the speed of sound in water?
depth, current, temperature, consistency (salt or fresh)
Why does salt water affect the way objects float?
salt water is different from tap water. when salt is added to water it converts the tap water to salt water. This increases the density of the water, and allows more objects to float above it. remember, when objects are mixed like that, the greater the density, the further it is from the surface.
How does salt effect an object float in water?
No, salt gets dissolved in water. Fresh water floats above salt water. In places with little mixing (fjords) there can be a several centimeter thick layer of fresh water above the salt water.
Do salt and acid act as a catalyst in rusting metals?
Salt acts as a catalyst. Acid tends to be a reactant.
Can salt affect metals?
yes it can.
Effects of salt on the rate of rusting?
The rate of rusting increases with the presence of salt.
How does salt water make metal rust?
oxegen in the air meets wih chemicals in the rock or metal and causes oxidation (the wearing down of rocks or rusting of metals
Does sugar water cause rust?
Iron is a highly reactive metal and when exposed to air, water and moisture, it starts reacting with them and forms rust. Basically rusting is the reaction of iron with oxygen and iron is nothing but iron oxide(Fe2O3). Iron things can be protected from rusting by using paints, galvanization etc.
How rusting of iron fast in coastal areas than deserts?
Rusting is strongly favored in humid atmosphere and also by the ion chloride from salt.
Will the medal get rustier with salt water or Regular water?
Although metals might not get 'rustier' placing a metal in salt water will increase the speed that metals will rust. This is because salt water contains minerals ions (i.e. Na+, Cl-) that increase the reactivity of the metal rusting. Metals rust by losing electrons to a contact fluid, i.e. air or water. Because of the ions in salt water there is a greater potential difference between the electon charge in the metal and the solution. This creates a simple kind of battery where the electrons will travel from the metal to the solution.
What are the effects of salt water vs chlorinated water when rusting iron?
it rusts
Why does road salt speed up rusting?
The chloride anion has a corrosive role.
Does copper rust faster in salt or fresh water?
yes it does because it rusts like all other rusting metals.
What accelerates the rusting process?
Wateroxygenhope this helped x
What happens when non metals react with metals?
they form a salt
