<h3>Entropy Change: What Is It?</h3>

Entropy change is a phenomena that measures the evolution of randomness or disorder in a thermodynamic system.
It has to do with how heat or enthalpy is converted during work.
More unpredictability in a thermodynamic system indicates high entropy.
Heat transport (delta Q) divided by temperature equals the change in entropy (delta S).

<h3>What causes variations in entropy?</h3>

When a substance is divided into several pieces, entropy rises.
Because the solute particles are split apart when a solution is generated, the dissolving process increases entropy.
As the temperature rises, entropy increases.

Answer:

Types of chemical weathering

1. Hydrolysis

2. Oxidation

3. Carbonation

4. Acid rain

5. Acids produced by lichens

Explanation:

Chemical weathering occurs when rocks undergo chemical reactions to form new minerals.

Hydrolysis : is when water dissolves minerals present in rocks forming new compounds.

Oxidation : is when oxygen reacts with rocks eg. rust formation

Carbonation : it uses an acid known as carbonic acid, it is important in the formation of many caves and sinkholes.

Answer:

Option (4) is correct

Explanation:

NaCl is an ionic solid. $Na^{+}$ and $Cl^{-}$ ions are held together by strong coloumbic attractive force. Hence NaCl has highest boiling point'
Ar is a monoatomic molecule. Hence only weak london dispersion force exists between Ar atom/molecules. Hence it requires lowest amount of energy to boil and thereby possess lowest boiling point.
$NH_{3}$ and $H_{2}O$ are polar protic molecules. Hence they possess london dispersion force, dipole-dipole force and hydrogen bonding as intermolecular forces.
Dipole-dipole force is stronger in $H_{2}O$ than $NH_{3}$ due to more polar O-H bond than N-H bond. Also molecular weight of $H_{2}O$ is higher than $NH_{3}$ . So, more energy is required to boil $H_{2}O$ . So, $H_{2}O$ has higher boiling point than $NH_{3}$
