the density
An object will float if it is less dense than the water (or other liquid). If it is denser than the water, it sinks.
No they will sink or break apart
It floats, but after a while silk will sink.
It depends on the type of rock. A rock like sandstone would not sink if it is a small peice. Small rocks can float. That's when its called silt.
A pencil floats, a human no float, a feather floats, paper floats, ice floats, keys do not float, rocks do not float, coins do not, flip flops float. Second answer: I think you meant to ask, 'What floats and then some time later starts to sink. If that is what you meant, the answer is: There are absorbent substances which float when dry, then after absorbing water while they are floating, they increase in density and then sink.
Hmmm. Canned/Tinned fruit will most certainly sink. Most fruits straight off from the tree will float. However, if the fruits are not ripe, they might sink as they are very dense. A coconut will most certainly float. A packet of biscuits (unopened) will float for a long time. Oatmeal flakes will float for a while, then sink to the bottom. Potatoes and carrots will sink. Lettuce and cabbage will float Regards.
Yes, it would actually float. While less liquids sink right to the bottom
you can put the mixture in water, the wood will float and the rocks will sink.
Whether an object sinks or floats depends on the objects buyoncy. If an object has a higher buoyancy then water it will generally sink, and less it will float.
rocks metal eggs dirt or sand all sink some woods sponge plastic aluminum cans all float
It all depends on the density of the object. If an object was less dense than water, then it will float. If an object is more dense than water, then it will sink.
things that are more dense sink while things that are less dense float
