Why a coin placed at the bottom of a beaker containing water appears raised?

It is an optical illusion due to the fact that water is more dense than air and so slows the speed of light. When light travels from a less dense to a more dense material, it slows down and 'bends'.

∙ 10y agothis is because of the phenomenon of refraction. when the ray of light from the coin travels from a denser medium to a rarer medium, it bends away from the normal.the point from which the refracted appears to come gives the apparent position of the coin. since the rays appear to come above the coin it appears to be raised.

What happens to air pressure if a balloon with the same initial volume is placed in a beaker of cold water then placed in a beaker of hot water?
it would shrink in cold and expand in warm, if you really want to surprise your teacher say it has to do with particle theory
Three different liquids and two equal sized cubes are placed in a beaker which of the objects has the greater buoyant force acting on it?
The answer is the beaker on the top because it has less mass
If an object floats in a beaker as shown assuming the graduated cylinder was empty when the object was placed in the beaker and the beaker was full to the level of the spout what must be true?
stop cheating on gizmos, fool. :)The Answer: The mass of the water in the graduated cylinder is equal to the mass of the object.lol
How is density of a liquid measured?
The density of a liquid can be measured with a beaker. the beaker is weighed alone, then a specific measured volume of the liquid is placed in the beaker and the beaker is reweighed. The difference between the beaker with and without the water is noted. from there the mass of the liquid for the specific volume is then known. using hte formula d = m/v, we can therefore determine the density. where m is in kg and v is in liters.
What is a displacement beaker?
a displacement beaker (canister) is used to determine volume of irregular objects. Water is put into the beaker up to the spout, and then an object is placed inside; the water that pours out is collected in a more accurate measurement device, this water is equal (or close to) the volume of the object.
What would happen to an animal cell if it was placed into a beaker containing a hypertonic solution?
You need dayan 2 hours
What would happen to a plant cell if it was placed into a beaker containing a hypertonic solution?
The plant cell would shrink but remain its shape.
When a crystal of copper sulphate is placed at the bottom of a beaker containing water the water slowly turns blue why?
The water gradually dissociates the copper sulfate, and copper ions in solution are blue.
Where should a beaker be placed with respect to the flame for the most efficient heating on Bunsen burner?
The most efficient, and safe, place for a beaker to be heated is above the flame. Have the beaker held up by the proper metal stand and have it held so that the flame is grazing the bottom of the beaker. Be careful though, the flame should only graze the bottom of the beaker so that the chemical doesn't heat up too quickly.
A potato cube is placed in a beaker filled with hot salt water and another potato cube is placed in a beaker filled with cold salt water?
A patato cube is placed in a beaker filled with hot salt water and another patato cube is placed in a beaker filled with cold salt water?
What is a beaker placed on top of?
a tripod
Where should a thermometer be placed in a beaker?
Hold it by the top or use a clamp. But make sure before you take the temperature you stir the liquid around in the beaker first and that you do not let it touch the bottom of the beaker as the glass will be hotter than your liquid.
What will happen when a drop of ink is placed gently at the base of a beaker containing water with the help of a dropper?
the ink will mix with the entire water.Even though it is dense than water,it will mix with it
When CuSo4 solution is placed in a beaker containing water it turns blue?
The molecules of copper sulphate solution mixes with the water molecules due to diffusion thereby making the water blue.
What happens if a cell is placed in a beaker containing isotonic solution?
well it would be that their is an equal amount of solution inside and outside the cell. it is neither hypotonic or hypertonic. it is balanced or equal.
What might happen to a heated beaker made from glass that does not contain boron if the beaker were placed in a pan of iced water?
The beaker has a high chance of shattering.
What happens to air pressure if a balloon with the same initial volume is placed in a beaker of cold water then placed in a beaker of hot water?
it would shrink in cold and expand in warm, if you really want to surprise your teacher say it has to do with particle theory
