dense, tightly packed molecules, maintains own shape and volume
Some can be.
Most solids shrink as they get colder (ice is an exception). Some solids become brittle when they are very cold and can shatter if struck.
since they are amorphus in nature
YES
Solids will transmit sound waves, some better than others. Therefore you can hear through some, though it depends on the material and thickness.
anything
density
covalent bonds and molecular solids are characteristic of organic compounds
porous is actually adjective which means having pores.porous solids are those solids which has porous nature.for instance alight soft foam.another characteristic of porous solids is that they absorb water like cotton so it is also a porous solid............
The rigidity of its structure.
Mass is in everything; gas, liquid and solid. Everything has some sort of weight, after all! You might be thinking of defined shape, which is a characteristic only solids have.
No. Surface tension is a characteristic of liquids, not solids like a juice box.
They are good conductors of heat and electricity. They have a metallic luster. All are solids except mercury.
they are NOT good conductors of heat and they are brittle solids.
Some solids are good conductors, some are not.
No. Some solids can be dissolved in water, some can't.
It is a characteristic of liquids and gases to assume the shapes of their containers while solids maintain their own shapes.
