The charge is a little negative
The highly compressible state of a matter is its gaseous state. The gaseous molecules are highly compressible due to presence of maximum space between the molecules than the other state of the same material. As for example the gaseous form of water that is vapor has the maximum space between the H₂O molecules and lowest in the solid state that is ice.
The motion of the particle have some postulates which is called the kinetic theory of gas. The gaseous particles of any particular gas can move independently in the vessel in which it is kept. The motion of the gas in a vessel is described by the Brownian motion.
The gaseous state of the material like carbon di-oxide (CO₂), oxygen (O₂), nitrogen (N₂) remains nearest to the earth surface which is stratosphere.
Answer/Explanation:
Experimental investigations are the best type of scientific investigation to demonstrate cause-and-effect relationships because they allow the investigator to actively manipulate variables and control conditions. This change can be measured to gather evidence to support or refute the cause-and-effect relationship. Experimental investigations also use a control group a group that does not receive the factor being tested for comparison.
Answer:
In the mixture of table salt, sand, solid iodine and iron fillings, iron filings is the only solid that is magnetic. Hence, it can be separated using a magnet. When a magnet is moved through the mixture, iron fillings get attracted to the magnet out of the mixture, leaving the salt, iodine and sand.
