which one of the following statements is correct? 1) Increasing of our body temperature is a reversible change. 2) Dissolution of gases like oxygen and carbon dioxide in water is irreversible change
Answers
Answer:
Dissolution of gases like oxygen and CO2 in water is irreversible change.....
Answer:
The first statement is correct while the other one is incorrect.
Explanation:
REVERSIBLE CHANGE-
A reversible change is a change that can be undone or reversed. These changes are observed in the physical state, size and shape of the substance. A reversible change does not create a new material.
1)Change in temperature is a physical change .The physical change are reversible in nature and can again be brought to their original state. So ,we can say that physical changes are temporary, and there is no change in their chemical properties ,but, are reversible can be reversed.
Thus, first statement is correct.
2)Dissolution of gases like carbon dioxide reacts with water molecules to produce a slightly acid solution called carbonic acid .
Dissolution of gases like oxygen and carbon dioxide in water is not a irreversible change.
And so, the second statement is incorrect.
