All metals are lighter than water if you have a lot of water and just a little bit of metal!
What you really mean to ask if what metals are less dense than water.
Several metals are not as dense as water. (The density of water is 1 gram per cm3 at 4 °C.) Here's the list:
lithium (Li), density: 0.53 g/cm3
potassium (K), density: 0.86 g/cm3
sodium (Na), density: 0.97 g/cm3
However, due to the extreme chemical reaction of these elements with water, you will never see any of these pure metals floating on water for any long period of time before you see a violent reaction, which in some cases will explode.
if the average density of the ship is lighter than that of the water
it is lighter than water.
i think mangoes aren't lighter than water
Ships, whether made of wood or metal, have a lighter specific gravity than water. Ships actually displace the water rather than floating on it.
Yes, Frozen water is 9% Lighter than actual water .
It's not! Oil is lighter than water, it's a density thing.
Oil is less dense and therefore lighter than water since it floats.
something that is lighter than the molecular mass of water.Mr of water= 2(1)+16=18therefore, anything with a Mr of lesser than 18 will be lighter than water vapour.example: hydrogen gas.Mr of hydrogen gas= 2(1)= 2therefore, it is lighter than water vapour.
Yes, gas is much lighter than water. The reason is that its larger molecules are much less dense than those of water.
No, water is lighter than mercury.
Because it's lighter than the weight of water, it can float over the water easily.
titanium, carbon fibre
Yes - Oil is lighter than water. Petrol, or gasoline, floats on water because it is lighter that water.
Coal can be heavier or lighter than water depending on its type. Most types of coal are heavier than water in terms of density, however, broken bituminous coal has only a density of 0.833 kg/m3, so it is lighter than water.
lighter...that's why oil mixed with water floats on the top
No. Oils are lighter than water.
plastic has less density than water
It depends on alcohol density. However, not all alcohols are lighter than water. Refer to link below.
Basically, if something is lighter than water, it will float. If the water is somehow made heavier, more things will be lighter than it. If you add a lot of salt to water, the body of water becomes heavier. Something that is heavier than water might be lighter than saltwater and float in saltwater but not normal water.
Frozen water actually has less mass then water so it would be lighter
It is lighter than water
