Explain Charles law​
kodGreya [7K]

"Charles Law" is the relationship between "volume-temperature" (V ∝ T).

<u>Explanation</u>:  

Charles Law is basically volume-temperature relationship (V ∝ T). French scientist “Jacques Charles” in 1787 studied effect of temperature on the volume of gases at constant pressure, which described how gases manage to expand when heated. Law stated as “At constant pressure, the volume of a given "mass" of a gas decreases or increases by 1/273 of its volume at 0^{\circ} \mathrm{C} for each one degree rise or fall in temperature”. Formula derived from law is as follows: \mathbf{V}_{\mathbf{t}}=\mathbf{V}_{0}[\mathbf{1}+\mathbf{t} / \mathbf{2} 7 \mathbf{3}] here {V}_{0} is volume of given mass of a gas at 0^{\circ} \mathrm{C}, {V}_{t} is its volume at any temperature t^{\circ} \mathrm{C}. Application of Charles law is hot air balloons.

For which compound is the process of dissolving in water exothermic?
Leokris [45]

Answer: Option (2) is the correct answer.

Explanation:

A chemical reaction in which reactants absorb energy is known as an endothermic reaction. Also, in this reaction energy of reactants is less than the energy of products.

For example, when ammonium chloride is dissolved in water then the solution becomes cold as the reaction is endothermic in nature.

Whereas a chemical reaction in which energy is released is known as exothermic reaction. Also, in this type of reactions energy of reactants is more than the energy of products.

For example, when NaOH is dissolve in water then heat is released as it dissociates into sodium and hydroxide ions. Further, product formed that is, species sodium and hydroxide ions acquire low energy state. Hence, the reaction is exothermic in nature.

Thus, we can conclude that NaOH is the compound in which process of dissolving in water is exothermic.
