Q5.
1. Compressibility · 2. Inflammability · 3. Fluid structure · 4. Burns with a blue flame · 5. Does not leave ash after burning.
Q6.
Iron
Q7.
Diffusion is the process because copper sulphate mixes up in the water and the solution turns blue. The process is called Diffusion.
Q8.
(b) 1 kg of copper
Q9.
CHLORINE.
Gases are more compressible than solids because gases have large intermolecular space and gas molecules are randomly located in the area, when pressure is applied the molecules get closer to each other decreasing intermolecular spaces and molecules getting organized. Hence CHLORINE gets compressed.
Q10.
Particles of copper don't diffuse because copper is a solid , so the inter-particle attraction is very high , because of which the particles cannot move about freely . Hence , they cannot spontaneously move and occupy the spaces between particles of other substance i.e. cannot diffuse .
