Ateacher did an experiment to show the movement of particles in solids, liquids, and gases. the experimental set-up is shown below: an inverted glass jar is shown. small circles representing foam balls are shown inside the jar. a stretched balloon is shown tied at the mouth of the jar. a string is shown drawn out from the middle of the stretched balloon. a hand is shown pulling the drawn out string. the teacher pulled the string attached to the stretched balloon, first slowly, then fast, and finally vigorously. which of the following is most likely correct about the pulling of the string and the corresponding state of matter being represented? gas is represented when pulled fast, solid when pulled slowly, liquid when pulled vigorously. gas is represented when pulled slowly, liquid when pulled fast, solid when pulled vigorously. solid is represented when pulled slowly, liquid when pulled fast, gas when pulled vigorously. solid is represented when pulled vigorously, liquid when pulled fast, gas when pulled slowly.

Answer is: Solid is represented when pulled slowly, liquid when pulled fast, gas when pulled vigorously.

For example, nitrogen molecules have weakest intermolecular bonds in gas phase and move fast and without order.

Cooling is change from liquids to solids. In solid state (for example ice) movement of molecules is more slow than movement of molecules in liquids (for example water).

In solid, molecules are closely packed, stiff and do not changes of shape or volume. Solid object (for example iron) does not take on the shape of its container.  

Liquids have definite volume, but no fixed shape.  

Gases (for example nitrogen and neon) not have definite volume and fixed shape, it depends on its container.

Solid is represented when pulled slowly, liquid when pulled fast, gas when pulled vigorously.

Explanation:

Hello,

The three states of matter could be distinguished via their molecular both arrangement and movement, in such a way, solids have an organized assembly of molecules that slightly and slowly move with respect to their equilibrium position, that is why the solid is represented when the string is pulled slowly, besides of their well-defined shape.

Secondly, liquids have a widespread longer distance between molecules and faster molecular movements which cause the liquid to have an indefinite shape, thus, the liquid is represented when the string is pulled fast.

Finally, the molecular arrangement in gases is "messy" as long as the molecules are in constant rapid motion causing both the crashing to each other and the indefiniteness of their shape. In such a way the gas is represented when the string is pulled vigorously.

Best regards.

water is used to store them because it would keep the radiation from getting out in the open and causing harm to the workers
