Answer:
The state of matter in Gas state has the greatest amount of particle movement.
Explanation:
Matter is classified generally in three states of matter and that is solid state, liquid state and gas state. So each state has its own properties and arrangement of atoms. If we consider solid state, the atoms will be bonded very close to each other and thus the movement of particles or atoms are very much restricted in a solid state. If we consider liquid state, then the atoms will be somewhat loosely bonded compared to solid and so the particles can be somewhat flexible to move from their original position. While for gaseous state, they are the most loosely connected state and so the atoms can move as freely as possible with no restrictions. Thus the gas state of matter has the greatest amount of particle movement among the given choices.
Answer:
160 m
Explanation:
distance covered in 1 s = 8 m
therefore, distance covered in 20 s = 8 * 20 m = 160 m
