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.
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
A cork is floating in salty water As more salt is added to the water to increase its density the cork will?
it float at the same level in water.
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.
Water waves can move a piece of cork floating on top of the water only in a up and down motion?
True
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)
Why does a cork float?
Cork floats because it is less dense than the liquid in which it is floating.
How does the mixture of sand and water form a suspension?
The sand remains insoluble and is visibly floating in the water.
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.
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.
A cork is able to float on water because it is?
A cork is able to float on water because it is less dense than the water. The reason why is because an object with more dense then itself it will float and an object with less density will sink in the fluid. HOWEVER if the object (such as the cork) has the same density, the object will neither float nor sink; instead it will stay at the same level in the fluid. So TECHNICALLY it is considered floating. So corks count as floating because it has less dense than the water. Sources: (Science: Glenco textbook)
Is cork an element compound heterogeneous mixture or homogeneous mixture?
Cork is considered a type of heterogeneous mixture. It is made from trees and other components, but it is inconsistent in composition.
