Forces of attraction between particles is the smallest in
olya-2409 [2.1K]

Answer:

The forces of attraction are weak in gases.

Explanation:

Solid-state objects are presented as bodies in a definite form; their atoms are often intertwined into narrowly defined structures, which gives them the ability to withstand forces without apparent deformation. They are generally described as hard as well as resistant, and in them, the forces of attraction are greater than those of repulsion. In the crystalline solids, the presence of small intermolecular spaces gives way to the intervention of the bond forces, which place the cells in geometric forms.

Solid – In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other.   Their vibration is related to their kinetic energy.  In the solid the particles vibrate in place.

Liquid – In a liquid, particles will flow or glide over one another, but stay toward the bottom of the container. The attractive forces between particles are strong enough to hold a specific volume but not strong enough to keep the molecules sliding over each other.

Gas – In a gas, particles are in continual straight-line motion. The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart and move freely of each other.  In most cases, there are essentially no attractive forces between particles.  This means that a gas has nothing to hold a specific shape or volume.

Calculating Velocity
m_a_m_a [10]

The average velocity of the object represented by the  distance time graph is 0.1\:meter\:per\:second

  • The velocity of an object is the change in the distance moved by an object with time.

  • This could also be related to the rate of change or slope of the graph.

  • Average velocity = \frac{change\:in\:distance}{change\:in\:time}

  • Average velocity = \frac{(5-0)}{(50-0}) = \frac{5}{50}=0.1\:meter\:per\:second

Therefore, the average velocity of the object is 0.1\:meter\:per\:second

Can an electron be found in an exact spot within an atom
jolli1 [7]
No, it is impossible to determine the exact location of an electron. This is because electrons don't have a definite position, and direction of motion, at the same time and its movements are unpredictable
