Answer:
Gas:
- assumes the shape and volume of its container
; particles can move past one another
- compressible
; lots of free space between particles
- flows easily
; particles can move past one another
Liquid:
- assumes the shape of the part of the container which it occupies
; particles can move/slide past one another
- not easily compressible
; little free space between particles
- flows easily
; particles can move/slide past one another
Solid:
- retains a fixed volume and shape; rigid - particles locked into place
- not easily compressible
; little free space between particles
- does not flow easily
; rigid - particles cannot move/slide past one another
Particles in a:
1. gas are well separated with no regular arrangement.
2. liquid are close together with no regular arrangement.
3. solid are tightly packed, usually in a regular pattern.
Particles in a:
1. gas vibrate and move freely at high speeds.
2.liquid vibrate, move about, and slide past each other.
3. solid vibrate (jiggle) but generally do not move from place to place

Based on the scientific method, for the scientist using radioactive dating to determine the age of a fossil, the best way to increase reliability is by doing repeated analyses of the fossil finding it to be the same age each time.
<h3>What is the best way to increase reliability of a discovery?</h3>
In science, the reliability of findings can be increased by taking repeated measurements.
In the case of the scientist using radioactive dating to determine the age of a fossil, the best way to increase reliability is by doing repeated analyses of the fossil finding it to be the same age each time.
