Question
Why does a boat float on water?Because the boat is lighter than the water.Because the boat is more dense than the water.Because the boat is less dense than the water.Because the boat weighs less than the water.
Solution
A boat floats on water primarily because of the principle of buoyancy. Here's a step-by-step explanation:
-
Buoyancy is a force exerted by a fluid (in this case, water) that opposes an object's weight.
-
When a boat is placed on water, it pushes aside (or displaces) some water.
-
The weight of the water displaced by the boat is equal to the buoyant force pushing up on the boat.
-
If the weight of the boat is less than the weight of the water it displaces, the boat will float.
-
This is because the boat is less dense than the water. Density is a measure of mass per unit of volume. A boat floats because it's designed to displace a lot of water compared to its weight.
-
Even though a boat may be made of materials that are denser than water (like metal), it's filled with a lot of air, which is much less dense than water. This makes the overall density of the boat less than that of water, allowing it to float.
So, the correct answer to your question is: "Because the boat is less dense than the water."
