Without seeing the piece of copper you have, it's hard to say.
An object will displace a volume of water equal to its weight. This is how a ship that weighs over 100,000 tons can float: the volume of the ship is greater than the volume of 100,000 tons of water. The ship pushes aside (or "displaces") 100,000 tons of water, and the rest of the ship rides above the surface.
Now for your piece of copper: If it's solid, the copper will weigh more than an equal volume of water. If it can't push aside water equal to its weight, it'll sink. If the copper is hollow, it will weigh less than an equal volume of water, and will float.
Of course. Fresh water floats on salt water, warmer water floats on cooler water, and ice floats on any water.
One method of determining if an egg floats in salt water is by dissolving salt in a container of water until the egg floats. Another method involves gradually adding salt to a container of water while placing the egg in to see if it floats. Both methods rely on the principle that the density of the water increases as salt is added, causing the egg to float when the water becomes dense enough.
Salt water is denser than fresh.
Copper chloride salt can be separated from water through the process of evaporation. Heat the solution of copper chloride salt and water until all the water evaporates, leaving behind the solid copper chloride salt.
It floats.
If you add the salt to the water, the density of the water increases. so the what ever floats on the water will come up. That mean it will get immersed in the water to less extent. If the salt does not dissolve in the liquid, like rock oil, there will be no difference.
freeze water as ice cubes then put it on water and it floats Liquid fresh water floats on salt water Warm water floats on cold water (water's greatest density is when it is 4 degrees Celsius).
an egg floats by its self
Salt water affects copper by causing corrosion. The non-oxidizing acids in the salt water break down the copper metal and in turn, the metal loses its color and begins to rust.
Anything whose density is less than that of the salt water u r taking.
Copper sulfate is dissociated in water.
Egg floats only when the density of the salt solution is almost equal to the density of the egg.The density is made equal by making the salt solution saturaed i.e by adding more salt so that the net mass increases and thus increasing the density. Thus by displacing a small amount of water,the egg floats
