I believe it is B.) a system of interacting subsystems or A.) An indivisible unit that is part of the solar system.
A substance floats if it is less dense, or has less mass per unit volume, than other components in a mixture. For example, if you toss a handful of rocks into a bucket of water, the rocks, which are dense compared to the water, will sink. The water, which is less dense than the rocks, will float. Basically, the rocks push the water out of the way or displace it. For an object to be able to float, it has to displace a weight of fluid equal to its own weight.
Water reaches its maximum density at 4 C (40 F). As it cools further and freezes into ice, it actually becomes less dense. On the other hand, most substances are most dense in their solid (frozen) state than in their liquid state. Water is different because of hydrogen bonding.
Answer: Your weight is increased.
Mass is the amount of matter that will always be the same everywhere. But weight is the force by an object that can be influenced by gravity. The gravity will increase in planet with more mass but will decrease if it has more radius/diameter.
