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 as these ions are freer to move inside an aqueous solution compared to Previous state.
Answer:
W= 638.1 J
Explanation:
As we know that
Work done is the area of the force and displacement diagram.
W=∫F.dx
W=Work
F=force
dx=Elemental displacement
From the diagram ,area A
A= 60 x 7.09 + 1/2 x 60 x 7.09
A= 638.1 J
So the work W
W= 638.1 J
