kolezko [41]

Answer:

The change in entropy of gas is $\Delta S= nC_{P}ln3$

Explanation:

n= Number of moles of gas

Change in entropy of gas = $ds= \int \frac{dQ}{T}$

$dQ= nC_{p}dT$

From the given,

$V_{i}=V$

$V_{f}=3V$

Let "T" be the initial temperature.

$\frac {V_{i}}{T_{i}}=\frac {V_{f}}{T_{f}}$

$\frac {V}{T}=\frac {3V}{T_{f}}$

${T_{f}} = 3T$

$\int ds = \int ^{T_{f}}_{T_{i}} \frac{nC_{P}dT}{T}$

$\Delta S = nC_{p}ln(\frac{T_{f}}{T_{i}})$

$\Delta S = nC_{p}ln3$

Therefore, The change in entropy of gas is $\Delta S= nC_{P}ln3$

Bond [772]

Answer:

Similarities

1. Fresh water and marine water both are essential parts of the water cycle.

2. They contain the same chemical and the amount of minerals in both the ecosystems is same.

3. Both addresses to the aquatic development.

Dissimilarities

1. Marine water carries much higher amounts of suspended chemicals as related to fresh water.

2. This larger collection of the chemical also increases the quantity of salt in marine water than that of fresh water.

3. Plant and animals existing in these water bodies also differ.
