- (i) Oxygen gas is more soluble in hot water rather than in cold water.
- (ii) A mixture of sand and water is a solution.
- (iii) The amount of space occupied by any object is called its mass.
- (iv) An unsaturated solution has more solute dissolved than a saturated solution.

Answer
Only (v) is true; (i), (ii), (iii), (iv) are false.
Explanation
| Statement | T/F | Correction |
|---|---|---|
| (i) Oxygen more soluble in hot water | False | Oxygen is more soluble in cold water. |
| (ii) Sand and water is a solution | False | It is a non-uniform mixture, not a solution. |
| (iii) Space occupied is called mass | False | Space occupied is called volume. |
| (iv) Unsaturated has more solute than saturated | False | A saturated solution holds more solute than an unsaturated one. |
| (v) Atmosphere gases form a uniform mixture | True | — |
Only the atmosphere statement is true; the rest are corrected as shown.
