What do copper sulphate crystals form when a hot saturated solution of copper sulphate is cooled?
Copper sulphate crystals form when a hot saturated solution of copper sulphate is cooled down. As the solution cools, the solubility of copper sulphate decreases, causing the excess copper sulphate to come out of the solution and form crystals.
If you used nitric acid to dissolve copper how could you remove the copper nitrate?
Heat the liquid to boil off excess water and the copper nitrate will crystalise out of the solution as it cools. Then filter to separate the crystals from the liquid.
Why do crystals form from copper sulfate?
Crystals form from copper sulfate when a saturated solution of copper sulfate is allowed to cool slowly. As the solution cools, the solubility of copper sulfate decreases, causing the excess copper sulfate molecules to come together and form a solid crystal lattice structure. This process is known as crystallization.
What will happen when copper is heated?
When copper is heated, it will expand due to increased molecular motion. If the temperature is high enough, copper will eventually melt and turn into a liquid state. Copper can also undergo a chemical reaction with oxygen in the air, leading to the formation of copper oxide on its surface.
How can the copper be changed back into a solid?
Copper can be changed back into a solid by cooling it down, either by letting it reach ambient temperature or by using a cooling agent like water or liquid nitrogen to speed up the process. As copper cools down, its molecules slow and arrange themselves into a solid crystalline structure, resulting in the formation of a solid piece of copper.
When will a telephone wire be longer summer or winter?
When metals (like the copper in the telephone wires) gets exposed to heat, they expand (thermal expansion) and when the get cooled they shrink. This directly implies that cables are longer in summer when it is hot. So telephone wires are longer in the summer.
How much does copper pipe shrink?
That would depend on the temperature /pressure as the coeffient of expansion per degree
What do copper sulphate crystals form when a hot saturated solution of copper sulphate is cooled?
Copper sulphate crystals form when a hot saturated solution of copper sulphate is cooled down. As the solution cools, the solubility of copper sulphate decreases, causing the excess copper sulphate to come out of the solution and form crystals.
The decrease in the volume of an object as if cools is called?
The decrease in the volume of an object as it cools is called thermal contraction. This occurs because as the temperature decreases, the particles in the object slow down, reducing the space between them and causing the object to shrink in volume.
How is copper concertration smelted in a modern commercial plant?
copper is smelted using a temperature of 800 -1000c it is then put into 3-6 containers then it cools down in the 3 containers
What geologic proccesses caused copper to form?
Copper is primarily formed through hydrothermal processes, where hot fluids containing dissolved copper minerals flow through cracks in rocks and deposit the copper as it cools. Another common way copper forms is through weathering and erosion of copper-bearing rocks, releasing copper atoms that can then be washed into sedimentary deposits.

Does lead shrink when frozen?
Yes, lead does shrink when frozen, but the effect is minimal. Like most metals, lead contracts slightly as it cools and solidifies, but this shrinkage is relatively small compared to other materials. The change in volume due to freezing is not significant enough to impact its practical applications.
When a piece of metal cools it will do what?
When a piece of metal cools, it will contract or shrink in size. This happens because the atoms in the metal lose kinetic energy and move closer together, leading to a decrease in volume. Cooling can also change the metal's properties, such as making it harder or more brittle.
What happens to a balloon when it is submerged in cold water?
When a balloon is submerged in cold water, the air inside the balloon cools and contracts, leading to a decrease in volume. This causes the balloon to shrink in size.
