Hot Water Temp can be till 45 deg C
Sodium shouldn't sink in water at room temperature, because the density of sodium is less than the density of water. The density of sodium at room temperature is 0.968 g/cm3, whereas the density of water at room temperature is 0.998g/cm3. So technically, sodium should float in water, not sink.

Yes, it may make oil sink if at some temperature the density of water goes lesser than that of oil.
Absolutely. Every built-in dishwasher can heat water to a higher temperature than what dispenses from your kitchen sink.

A density greater than that of water (which varies with temperature).
It varies from cold water which is normally 40 degree Fahrenheit to hot water which in a sink is normally 110 degrees Fahrenheit
the density of the water, temperature (warm temps) and salinity (amount of salt in the water) could make ocean water sink (-:
you put baking soda and smosh it and drop it into the water and it should sink
yes, if the metal is gold it will sink
I recommend that you use a sink full of foamy water at a temperature of about 50oC.
It should be thawed in a fridge, but if you are in a hurry, then put it in a sink filled with cold water. This is faster than no water and safer.
