6) The answe is about waste materials or garbage
A. they are toxic when not disposed properly.
A. They are toxic when not disposed properly
its because of how compact the particles/molecules are in the said object, but not all solids can't dissolve
Materials that can't stretch or bend much without breaking are said to be brittle. Copper is quite ductile, which is part of why it is used for wires (most metals are ductile (but copper especially so). Glass and ceramics are often brittle; they will break rather than bend.
the particles of matters are so close and in form of solid matter.
Chemical liquid can dissolve solid material.
(Well search some)
because they are having strong combination of particles.
A solid will not dissolve in a liquid if its particles are unable to form links to the liquid particles. The simple particle model is less helpful in explaining why there is a limit to the solubility of any material or why the solubility varies at different temperature.
mantle and it has 2 parts (outer and inner mantle)
they are grouped by the noise they !
