Which one of the following statements is correct ?

Statement 1: Increasing of our body temperature is a reversible change

Statement 2: Dissolution of gases like Oxygen and Carbondioxide in water is irreversible changes.

 Statement – 1

Statement 1: Increasing of our body temperature is a reversible change.

This statement is correct. The increase in body temperature is an example of a reversible change. Reversible changes are those that can be undone or reversed, meaning the substance or condition can return to its original state. In the case of our body temperature, when we experience a temporary increase in body heat, our body regulates and brings it back to a normal temperature, either by sweating or other physiological processes. For instance, if we have a fever, once we recover, our body temperature returns to normal. Therefore, this is a reversible change.

Statement 2: Dissolution of gases like Oxygen and Carbon dioxide in water is an irreversible change.

This statement is incorrect. The dissolution of gases like oxygen and carbon dioxide in water is actually a reversible change. When gases dissolve in water, they can later be released back into the atmosphere by various processes, such as heating the water or reducing the pressure. For example, when we open a carbonated drink, carbon dioxide gas dissolved in the liquid escapes, and this can be reversed if the gas is trapped again under pressure. Thus, this process is reversible and does not lead to an irreversible change.

• Statement 1 is correct: Increasing body temperature is a reversible change.
• Statement 2 is incorrect: Dissolution of gases in water is also a reversible change.
