How does a canoe float on water?
Same way as anything else - displacement, in that the mass of water displaced by the canoe's hull is greater than the mass of the canoe itself. This means the canoe is effectively less dense than water and so has positive buoyancy and will float.

Any boat made of a heavier than water material can float if it meets a few basic requirements. The first requirement is that the total volume of the boat must be greater than …the weight of water that volume would displace. The second requirement is that the boat must not permit water inside. There are additional details but these two are the biggies. Here is an example: A 20 foot canoe has an overall displacement (volume) of 40 cubic feet. That is equal to approximately 320 gallons, or a weight of 2,560 pounds. Concrete weights vary somewhat but using a number of 150 pounds per cubic foot, as long as the total amount of concrete used is less than 2,560 / 150 or about 17 cubic feet, the boat could float. If the sides and bottom of the canoe are 2 inches thick and the bottom area is 50 square feet and the sides also total 50 square feet, 100 square feet total times 2/12 foot thickness gives about 16.6 cubic feet of concrete. This would just barely float.
Lie on your back and relax! :
Ice (solid water) floats on liquid water. Fresh water floats on salt water (less salty floats on more salty). Warm water floats on cold water. I was in a fjord in northern… Norway some summers ago and the glacial runoff (fresh water) floated on the sea water of the fjord. A layer about 3 centimeters thick on top of the water in the inner part of the fjord was not salty at all ( I tasted it). When you stirred you could see the differences in optical density too. This also caused trouble for boats as hydrodynamic drag increases noticeably when there is a layer of fresh water on top of the salty water.
You just answered your own question. It floats.

because ice has less dense than water
A boat can float on the water, and a submarine can float in the water.
sometimes . . . Its the only liquad in its solid form to float on its liquad form. This is because water forms hydrogen bonds, which form large spaces of air, creating the ice… to be less dense then liquad water. this is just a joke don't write this I'm just messing with you
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).
Answer Because on average you are less dense than water. That is why anything floats on anything else. It is also true that the weight of the water you displac…e is equal to your weight.
It depends on the species. Lily Pads have a flat surface area which allows them to float on the surface like a boat as well as having stems that keep growing until they… reach the surface and then stop growing. With many Kelp species, they have "float sacs" filled with air which allow them to stay afloat.
Yes.It is a water plant which floats.
An aquatic plant bubbles because it releases oxygen bubbles. The oxygen bubbles float to the surface of the water and get released in to the air.
If you put water into water, it would eventually get mixed. Fresh water is less dense than salt water and fresh water from rain or rivers will "float" on underlying salt sea… water. Water of different temperature and different salinity have different densities and do make layers in the oceans and lakes of the world. Ordinary water will usually mix rather than separate, unless it is frozen into ice, which is less dense than liquid water. There is also "heavy water" that has deuterium in the place of ordinary hydrogen and is ABOUT 11% denser than ordinary water, which will float above it.
Objects that are denser than water, do not float on water. Water= 0.9grams repeated or even 1.0grams.
Take a fluids class
You are at the front of a floating canoe near a dock You jump expecting to land on the dock easily Instead you land in the water Explain in terms of momentum conservation.?
When you jump forwards you push back on the canoe, which then tends to drift backward as you jump off. So, effectively, you move slower relative to the water since … the base you are jumping from is moving backwards. Of course, the canoe moves backwards to be consistent with conservation of momentum. Originally there was no momentum when you were standing still, so if you gain momentum forwards, the canoe must gain momentum backwards, assuming no external forces are acting.
