The particles of a liquid are packed more closely together than the particles of a gas and therefore don't have as much movement. O A True O B. False no links​

A. True

Explanation:

We are talking about motion of solid, liquid and gas particles.

Now, for gas particles, due to the fact that it's particles are far apart from one another, it usually vibrates and thus moves freely at speeds that are higher than those of liquids of solids. For liquids, their particles are not as far apart as those of gases and so they vibrate, move about, and then slide past each other while solids are the most densely packed and so they vibrate but do not move from one place to the other like gases and liquids.

Thus, we can see that particles of liquid are more closely packed than gases and as such don't have same movement speed.

a and b sometimes have a positive value

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
