System A undergoes an increase in entropy while system B undergoes a decrease in entropy.
Entropy is the degree of disorderliness of a system. The entropy of a system depends on the number of particles present in the system as well as the state of matter.
Entropy is increased when solid particles dissolve in water because more particles are produced thereby increasing the level of disorderliness in the system.
On the other hand, when vapor is condensed, the degree of disorderliness decreases as gases are converted to liquids.

Answer:
1.7 ppm
Explanation:
Original amount N' = 2.6 ppm
time to testing t = 24 hr
final amount N = 2.1 ppm
Using exponential inhibited decay, we have
N = N'e^(-kt)
Where
N is the new reading
N' is the original reading
t is the decay time
k is the decay constant
Substituting, we have
2.1 = 2.6 x e^(-k x 24)
2.1 = 2.6 x e^(-24k)
0.808 = e^(-24k)
We take the natural log of both sides of the equation
Ln 0.808 = Ln (e^(-24k))
-0.213 = - 24k
K = 0.213/24 = 0.00886
After 48 hrs, the reading of free chlorine will be
N = 2.6 x e^(-0.00886 x 48)
N = 2.6 x e^(-0.425)
N = 2.6 x 0.654
N = 1.7 ppm
Answer:
photoelectric effect, phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation. The effect is often defined as the ejection of electrons from a metal plate when light falls on it.
Party realignment a shifting of party alliances within the electorate.
<h3 /><h3>What is party alliances?</h3>
An electoral alliance is a grouping of political parties or individuals who get together primarily to run for office in elections. It is also referred to as a bipartisan electoral accord, electoral pact, electoral agreement, electoral coalition, or electoral bloc.
Founded in 2019, the Alliance Party is a centrist American political party. It is connected to the American Party of South Carolina, the Minnesota Independence Party, the Connecticut Independent Party, and the Florida Reform Party.
