Explain the method to find the volume of a cork floating in water?
Step 1: Fill a graduated cylinder with water Step 2: Measure how much water is in the cylinder Step 3: Place the cork in the water Step 4: Measure the amount of water again Step 5: Subtract amount of water without cork and amount of water with cork regular- cork = volume of cork This method is called water displacement.
Is cork float or sink in water?
If you dropped a cork in a container of water, the cork will most definitely float. As to the cork is lite, like a feather and it doesnt container much mass.
Can you make water light enough to sink a cork?
no
Why cork floats in water?
Any object placed in water will be pulled down into the liquid by gravity. But an object less dense than water will only be pulled down until the object displaces an amount of water equal to its own mass. Then it will float. The water will be pushing up equal to the force of gravity pulling down - an equilibrium. Any object that weighs less than its own volume of water will float. It's lower overall density will result in buoyancy.
Which of the following is not a mixture a. pure water b. seawater c. air d. brass?
Answer a. Pure Water is not a mixture - it is a compound. Seawater is a mixture of water and salts, air is a mixture of gases and brass is a mixture (an alloy) of copper and zinc metals.
D the floating of cork in water what is the principle behin?
the density of the cork is lower than the density of the water- so it floats.
How is the weight of water displaced by a floating cork related to the buoyant force on the cork?
The weight of water displaced by a floating cork is equal to the buoyant force acting on the cork. This relationship is described by Archimedes' principle, which states that the buoyant force on an object is equal to the weight of the fluid it displaces.
Which has less density a cork or water?
A cork is less denser than water because cork is floating on water so it will have less density than water
Why do you float magnetised needle to a cork floating in water?
When a magnetized needle is placed on a cork floating in water, it aligns itself with the Earth's magnetic field. This allows the needle to point north-south, making it a simple compass. The buoyant force from the cork keeps the needle afloat without sinking.
A cork is floating in salty water As more salt is added to the water to increase its density the cork will?
sink, as the increased salt concentration will make the water more dense. This increased density will reduce the buoyant force acting on the cork, causing it to sink.
Why does a cork float?
Cork floats because it is less dense than the liquid in which it is floating.
Is volume of liquid displaced by a floating cork more or less than the volume of the cork?
If the cork is floating, then part of it is underwater and part of it is abovewater. The part that's above water is not displacing water, so the volumedisplaced is less than the total volume of the cork.Here's a mantra that will, come in very handy if you memorize it and thenfile it away until you need it:"A sinking object displaces its volume.A floating object displaces its weight." I can't think of any way that an object in water could displace morethanits volume.
How does the mixture of sand and water form a suspension?
The sand remains insoluble and is visibly floating in the water.
How do you seperarate a mixture of sand salt iron filing and cork?
For the nails, you can use a magnet. You can separate the marbles and corks by putting it in water, wood floats and marbles don't.
Is ocean water a substance or mixture?
Mixture (in addition to being a mixture of salt and water, theres a bunch of other goodies floating around in it)
How A cork is floating in a saltwater solution As more salt is added to the water to increase its density what happens to the cork?
As more salt is added to the saltwater solution, the density of the water increases. Eventually, the density of the saltwater solution becomes greater than the density of the cork, causing the cork to sink. This is because denser objects tend to sink in less dense fluids.
Give the effects of buoyant force of liquids on solids less dense than the liquids?
See if the solid is less dense than the liquid, like a cork floating on water or a log of wood floating on the water. The buoyant force acts on the cork or the wood and overcomes the force exerted due to acceleration due to gravity because of which these things float.
