a fine powdered solid
Yes it is a good absorber. There are many reasons why it is a good absorber. One of the reasons is because it is very porous.
Mercury's state of matter is a liquid. Mercury is not a good conductor of heat and cinnabar is the largest natural source for mercury.
No state of matter corresponds to this. Solids are the only state with definite shape, but they have a definite volume too.
it absorbs moisture which may be caused by heat it may also be a good absorber for dirt and dust
Ionic compounds are good electrical conductors in the liquid state.
No drywall is not a good shock absorber. It's too rigid.
No, you can be both good and evil. This is the same concept. The object is either a good absorber or a good reflector, and can not be both. Black is a good absorber, white is a good reflector.
There are free ions in the liquid state of ionic compound, hence the are good conductors of electricity.
Yes it is.
Ionic compounds have good electrical conductivity in the liquid state because the ions are free to move and carry an electric charge. In the liquid state, the ions are not held in fixed positions like in the solid state, allowing them to flow and conduct electricity.
States can be ranked in order of importance only depending on the application. For example, in a steam engine the steam must be in its gaseous state; liquid or solid water would be no good. On the other hand for a concrete reinforcing rod the solid state is important, essential really. Liquid is essential for beverages which are to be drunk.
During a phase change, a substance transitions from one state of matter to another, such as from a solid to a liquid.
