Pumice is a porous rock that can float on water. It's density is less tham 1g per cm.
C. A bowl filled with apples is the more porous of the four. Porosity is a function of the size of the fruit. The larger the fruit, the more porous the bowl will be (the more air or water that can be placed in the bowl). The smaller the fruit, the less porous the bowl will be. Compare with a bowl of stones and a bowl of sand. The stones are more porous because the sand can be more densely compacted, leaving very little room for water.
If water droplets penetrate within 3 minutes or less it is considered porous, if water droplets remain on top it is considered non porous..

Oak is dense and considered a hardwood. That being said, it can absorb liquids, making it porous but, not as poroius as say plywood or mdf.
it would make a fart noise and die ha ha
The Gravel will absorb the water until it can absorb anymore.
you can wait until the water evaporates
No, the gravel sinks when placed in water and is therfore more dense than water. This means that given two equivalent volumes one of water , one of gravel, the mass of the gravel will be greater than that of the water.
It would die. Frogs have a porous skin and the slat in the sea water would quickly kill it, because fogs are adapted to live in fresh water.
you get gravelly water
Nothing will happen to a a raw egg when placed into sparkling water.
it will die
No, it does not.
