Does copper particles contain kinetic energy?
the particles in copper only have kinetic energy once it has been heated as this causes the particles to move around (kinetic energy) knocking its neighbour causing heat
Describe the appearance and odor of the liquid obtained by heating copper 11 sulfate pentahydrate?
Describe the appearance and odor of the liquid obtained by heating copper II sulfate pentahydrate.
Why does copper sulfate change mass when heated?
Solid copper appears to gain mass when heated in air, because the copper reacts with oxygen in the air to form copper oxide. However, the actual mass of the copper does not increase; the mass of the solid increases by a value equal to the mass of oxygen removed from the air.
Which two characteristics describe copper patch panels?
RJ-11 and RJ-45
What word is used to describe a mixture that is 85 percent copper and 15 percent tin?
Alloy
What happens to the particles when you mix copper sulphate and iron?
Diffusion occurs - The particles of copper sulphate move between the particles iron because the particles are tiny and discrete.
What process obtain tiny particles copper sulphate from copper?
Crystallization
Describe the functioning of copper zinc electrochemical cell?
describe the functioning of copper zinc electrochemical cell
When a crystal copper sulphate is placed at the bottom of a beaker contaning water the colour of water slowly becomes blue?
The spreading of blue colour of coppersulphate crystals in water is due to movement of water paticles as well as coppersulphate particles.due to the movement of particles the coppersulphate crystals and water particles mix with each other this is called diffusion.diffusion takes place untill the whole water obtain blue colour.
Does copper particles contain kinetic energy?
the particles in copper only have kinetic energy once it has been heated as this causes the particles to move around (kinetic energy) knocking its neighbour causing heat
Briefly explain why is bronze much harder that either copper or tin?
nether.tin is a rock
Is the attraction between steel particles stronger than the attraction between copper particles?
yes
Why are particles close together?
The particles in copper are close together because it is a type of solid. Solids have a definite shape and mass. Copper is a type of metal, which is a great conductor. Any item with hardness is a solid, for copper is a solid
What happens to copper sulfate particles when they dissolve?
they fly away
Why do particles vibrate?
The particles in copper are close together because it is a type of solid. Solids have a definite shape and mass. Copper is a type of metal, which is a great conductor. Any item with hardness is a solid, for copper is a solid
What happens to the particles in copper when heated by a Bunsen burner?
[object Object]
How does soil filter out copper?
The copper particles stick to the soil, while the water continues to filter through the soil. Therefore the copper stays in the soil while the water does not.
