Question

Observation and conclusion of matter

Answer 1

Answer:

The observer effect is the theory that the mere observation of a phenomenon inevitably changes that phenomenon[1]. This is often the result of instruments that, by necessity, alter the state of what they measure in some manner. A common example is checking the pressure in an automobile tire; this is difficult to do without letting out some of the air, thus changing the pressure. Similarly, it is not possible to see any object without light hitting the object, and causing it to reflect that light. While the effects of observation are often negligible, the object still experiences a change. This effect can be found in many domains of physics, but can usually be reduced to insignificance by using different instruments or observation techniques.

All matter is made up of atoms . Whether a substance is in solid , liquid and gas state depends on the arrangement of the atoms ..... The particles that make a gas are separate from each other and move freely . This makes gasses very easy to compress.
