vfiekz [6]

Answer:

Explanation:

When we add salt to water entropy of the system increases because some amount of energy is released as salt dissolves in the water due to the dissociation of ions.      

Therefore entropy of the system after the salt dissolves is highest among them all and the least entropy is associated when mixing begins.

Entropy is the degree of randomness and it increases when salt dissociates to Na^{+}\ and\ Cl^{-} as these ions are freer to move inside an aqueous solution compared to Previous state.

Which statement is true of AC current?. Select one of the options below as your answer:. . A.. It uses a battery as a power sour
Nonamiya [84]
<span>The answer is B. It can be converted from high to low voltage and vice versa using transformers. That is why high voltages (tens or hundreds of kilovolts) is used to efficiently transfer electricity for large distances and then converted to 110-240V.

The answer can also be derived by elimination. [A] is not right because battery provides only Direct Current (DC). [C] is not right because high voltages are used for AC (from 110V to hundreds of kilovolts). [D] is not right because as the name Alternating Current suggests, the current is alternating in its direction. [E] is not right because DC was the first type of current invented.</span>
