Why can a metal boat float?

Question

Explain thouralghy!!

Answer 1

metal boats are made out of aluminum a very light weight metal.  When placed on water they displace the water thus not allowing the boat to sink

Answer 2

try this

take two peices of aluminum foil from the kitchen

wad one up, it will sink

all metal is heavier than water and cannot possibley float

not shape the other peice of foil over a small bowl or tennis ball, it will float

the part about displacement was very well explained above but perhpas this demonstration will help you see it

Answer 3

Learn to spell.

Let me explain THOROUGHLY.

Because it displaces water.

There...done!

If it does not leak...and it is configured to displace water...it will float. Add water until it no longer has bouyancy greater than it's displacement...it will sink.

On perfectly still water...perfectly still...as a laboratory test pool....a sheet of steel that is perfectly flat will still  lay on top of the water as long as it is laid on the water perfectly flat...lowered from above. As long as it does not tip and there is no ripple...that is...nothing breaks the surface tension...the sheet will float.

Answer 4

bouyancy and water displacement, the more water you displace the more something can weigh.

ie.Every substance has density, including water. If the density of a given object is greater than the density of the water around it, it sinks. If it is less, it floats.

Answer 5

Because its a Witch!

Burn the witch!  

Its a scientific Fact!

Boats float

Ducks float

wood floats

wood burns

so if a boat floats it must weighs less than a duck and is therefore a witch...

burn the witch.

Answer 6

Displacement The boat replaces where water is because of it's weight. Not enough to sink but enought to float.
