Are coins iron or steel?
Iron rusts easily, so coins are rarely made of that metal. However, many countries use steel in their coins, among them the UK, Canada, and the EU.
Why isn't rust attracted to a magnet?
Rust is mostly hydrated Fe2O3 and is not "ferromagnetic" (forming strong magnetic fields) because the atoms of iron are separated by the atoms of oxygen (and molecules of water). However, rust (and the Fe2O3 mineral hematite) responds to an electromagnetic field, and the weak attraction is now being used to separate hematite from waste ore, increasing the amount of iron extracted from a given amount of ore.
What is a chemical and physical change?
Physical change - a change in a substance that does not involve a change in the identity, including a change in state between solid, liquid and gas phases.Chemical change - a change which one or more substances are converted into different substances, some indications are burning, rusting, color changes etc.physical change can be changedbut in chemical change chemicals are mixed togetherfor example if we are sick that is a physical changewe have to change healthy as wellwhen we mix salt in a dish,can we take out that again?neverthis is chemical changeA physical change is when the object undergoes a change that can be reversed, such as mixing water with salt, melting ice, or freezing or vaporizing water. A chemical change is a change that changes a substance into something else entirely, and therefore cannot be reversed. Examples would be mixing vinegar and baking soda or turning batter into bread.chemical change is when during a chemical reaction a new substance will be formed while in physical change no new substances are formed
How are physical and chemical changes different in two ways?
a physical change can be reversed but a chemical changes is not. you can all tell the different from a physical and chemical change by seeing if the color or if the substances is still in it normal element and it a chemical change if it has been change to a new substances like a burn paper change to Ashes. It is all most a physical change but it can not be reversed back.

When iron rusts does its weight increase or decrease?
Actually it doesn't affect its weight at all. During the chemical change that occurs when iron rusts, the weight does not change because weight never changes during a chemical reaction because nothing new is being created nor destroyed, only combined.
