Well, a good boat is.
Ice floats in water because it is less dense than water. A wooden boat floats on water because it is less dense than water. A balloon filled with helium gas floats in the air because it is less dense than the surrounding air. A cork floating in water floats because it is less dense than water. A rock sinks in water because it is more dense than water.
A boat floats because it is less dense than the water it displaces. The upward force acting on the boat from the water is called buoyancy, which counteracts the force of gravity pulling the boat downward. As long as the weight of the boat is less than the weight of the water it displaces, the boat will float on the surface of the water.
Ice is less dense than water
Because the boat has a special shape that makes it less dense than water.
flotation is due to the fact the boat is less dense than the water, salty water is more dense than normal water. Consequently things can be heavier or more dense and still be less dense than water aka they float.
A boat can float because it is made of materials that are less dense than water. This means that the boat weighs less than the amount of water it pushes aside, allowing it to stay on top of the water instead of sinking.
A wooden block can be less dense than water.
no
Oil IS already less dense than water.
Easy, put a fruit in water and if it floats it is less dense than water.
Plasticine is less dense than water, so it displaces an amount of water that is equal to or greater than its weight. This buoyant force keeps the plasticine boat afloat on the water's surface.
Yes. Anything that is less dense than water will float on water.
