Chemistry - Thermochemistry Question with Solution | TestHub

Dissolution of a gas is similar to condensation: the gas molecules lose freedom and release heat. Consequently, gas solubility decreases as temperature rises (according to Le Chatelier's principle), confirming that the dissolution of gases is an exothermic process. Therefore, Statement 1 is correct. Gases are generally only sparingly soluble in liquids (e.g., O_₂, N_₂, H_₂ in water), which means Statement 2 is incorrect. The final answer is (c).
