A whale is not a fish. It does not have scales on it's body nor does it have gills.
A whale is adapted to live in water because, whale has lungs, which it uses for breathing. Because of this, a whale has to swim to the water surface to breathe.
whales have bladder inside them which help them to float
when they are on the surface of water they fill it with air which decrease their average density but when they have to go inside the water they release air and fill their bladder with water as required.
this may or may not satisfy your question
i just only don't know how they come back to the surface as they can breath only on surface once they go inside the water then how will they fill their bladder back with air
Their blubber creates a natural buoyancy
because is big and cool to look at
Record how high the foam floats in water.
Oil floats on water because water is denser than oil.
a ship
Hint: It floats in water.
Vinegar
Yes. It floats on water
Of course. Fresh water floats on salt water, warmer water floats on cooler water, and ice floats on any water.
It is less dense than water, therefore it floats on water.
kerosene floats on water because kerosene is less denser than water
the density of water is higher than the density of wood... & so an iron piece sinks & a ton of wood floats...
Record how high the foam floats in water.
freeze water as ice cubes then put it on water and it floats Liquid fresh water floats on salt water Warm water floats on cold water (water's greatest density is when it is 4 degrees Celsius).
The reason why ice will float in water is because ice is not as dense as water, therefore, it floats.
Yes, paper is less dense than water, so it floats.
Ice is less dense than water, so it floats.
they used boats and floats, ICECREAM FLOATS
water is less dense than vinegar , so it floats
