Answer:
<h3>In a solid, molecules are packed together, and it keeps its shape. ... Matter is the "stuff" of the universe, the atoms, molecules and ions that make up all physical substances. In a solid, these particles are packed closely together and are not free to move about within the substance.</h3>
The correct statement is <span>(4) All atoms of a given element must have the same atomic number.
Atoms come in different isotopes(which have different mass), which differ in the number of neutrons, but are still the same element (this tells you why the other options are bad).

Answer:
-100 K
Explanation:
<em>Kinetic energy is related to temperature.</em> The molecules in water will move faster in warmer temperatures than in colder ones.
100 K is equal to -279.67°F (-173.15°C). So 100 K would have the lowest average kinetic energy.
The reaction starts with Anisole which is ortho-para directing group. So reacting anisole with Con H2SO4 and con HNO3 gives paranitro anisole.
Now paranitro anisole is a meta directing group and having low electron density in meta position which on reacting with Cl2 and anh AlCl3 directs the chlorine to meta position of nitro group and results in formation of the product 2-chloro-4-nitroanisole.
Thus, the product is 2-chloro-4-nitroanisole
