true
False. Objects sink in water because they are more dense than water.
Water is denser than oil, so yes, it will sink. That is true whether the water is inside a balloon or not.
Thats not true. Salt water is more dense than fresh water so the boat wont sink as much
200 ppm
cold water is denser than hot water. The same is true of most other substances as well.
I do not see why not. It IS blocked, isn't it! Actually the sink is never blocked as water can always go above the floor level. It would be better to say the fixture has a stoppage / blockage either in the trap or the waste pipe Scientifically that is true, but the fact is that water can NOT so through (down) the 'hole.' Hence it IS blocked!
Being heavier (denser) than water, it would sink.Being heavier (denser) than water, it would sink.Being heavier (denser) than water, it would sink.Being heavier (denser) than water, it would sink.
This is actually not true at all times or for all sharks. It is true that most sharks need moving water in order to breathe, but there are underwater currents where sharks can stop, because the water is moving around them.
A heat sink is a device that allows the transfer of heat away from the heat source. It can be in the form of a paste or jelly or a simplealuminum structure which is attached to the heat source. Virtually all microprocessors in computers utilize a heat sink to transfer the heat of the CPU to the aluminum which can 'shed' that heat into the air (air transfer method). Some CPUs are water cooled; one might say that this is a 'water heat sink' but that really isn't true.
true
It is true. An example is in quicksand, were sand grains are separated by water (upflowing spring, etc) so making the surface unstable.
