Suppose you found a yellow piece of metal in a stream how can you tell if it's real gold

Hello!

The quickest and simplest way would be to take it to a jeweler or pawn shop and get it checked.

However, another way is: make a light, tiny scratch on the item using a small nail file or similar rough object. Choose a spot that is not noticeable if you want to keep it's value. apply a small drop of nitric acid to the scratch (use a dropper if you have one)

If there is no reaction, then the piece is probably made from real gold

I hope this helps, and have a nice day!

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
