Muscle does not weigh more than fat, any more than lead weighs more than feathers. A pound is a pound is a pound. Where the misunderstanding often comes in is that muscle is much more dense than fat, so that, by volume, it seems to weigh more. That is, a pound of muscle occupies less space than a pound of fat. In addition, because a pound of muscle burns more fat than a pound of fat, even at rest, by increasing your lean muscle tissue mass, you're helping your body burn more calories. But back to your question.
Since this one has more marbles for each box part (4) than the first one (3), we can say that the second one is DENSER. Salinity adds to mass (no. of marbles) but not to the volume (size of box). Thus, the more salinity, the denser. Temperature may also affect water density. When the temperature is high, molecules in water disperse and move around more rapidy than they usually do in order to spread the heat energy.
