Discussion
Densities of four liquids A, B, C and D are given below :
| Liquid | A | B | C | D |
| Density (kg/m3) | 785 | 820 | 924 | 1020 |
Based on this information, identify the correct statement from the following :
Answer: A
The correct statement is that an object that floats in liquid C may or may not float in liquid A.
An object floats in a liquid if its density is less than the liquid's. An object floating in C (924 kg/m³) has density below 924; it will also float in A (785) only if its density is below 785, so it may or may not.
The other statements fail. An object floating in A has density below 785, so it surely floats in the denser B; 'may or may not' is wrong. An object floating in B (below 820) need not float in the less dense A, and one floating in C (below 924) need not float in B (820).
