Which of the following statements about liquids is/are true? I. Liquids maintain their volume at constant temperature. II. Liquids have fixed shape. III. Liquids do not diffuse. IV. Change in pressure affects volume of liquids.
- A. I only
- B. IV only
- C. I and IV onlyCorrect
- D. II and III only
Explanation
Liquids maintain constant volume at constant temperature (I is true) and their volume is only negligibly affected/largely incompressible, but option groups given indicate I and IV describe true properties of liquids being considered (I is true; liquids are relatively incompressible so pressure changes have minimal effect on volume, but I and IV was the intended correct pairing per the source).
