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'.
The air pressure inside the balloon will decrease when placed in cold water, as the air molecules cool and move closer together. Conversely, the air pressure will increase when the balloon is placed in hot water, as the air molecules heat up and move further apart.
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.
The density of the material is greater than the density of water if it sinks to the bottom of the container when placed in water.
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
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.
You need dayan 2 hours
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.
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.

The iodine solution in the baggie would diffuse into the beaker containing the starch. The iodine molecules would interact with the starch molecules, resulting in the formation of a dark blue or black color, indicating the presence of a starch-iodine complex.
The copper sulfate crystal will dissolve in the water to form a blue solution. This process involves the breaking of ionic bonds in the crystal structure and the hydration of copper ions and sulfate ions. The resulting solution will be homogeneous and show a blue color due to the presence of Cu2+ ions.
The temperature of a beaker is typically measured using a thermometer that is placed in the water inside the beaker. The thermometer will provide a reading of the water temperature, which indirectly reflects the temperature of the beaker as well.
when iron nails are kept in a beaker containing copper sulphate displacement reaction takes place.Iron is more reactive than copper so it displaces copper from the copper sulphate solution.Thus it becomes iron sulphate+copper
The spots on the TLC plate should be placed about a cm from the bottom of the plate. Then solvent should then fall about half-way between these spots and the bottom of the beaker.
When an inverted beaker is placed over a lit candle, the flame goes out due to lack of oxygen. As the candle burns, it consumes oxygen and generates carbon dioxide and water vapor. When the beaker is placed over the candle, it creates a closed system, limiting the supply of oxygen needed for combustion, causing the flame to extinguish.
the egg become bigger if they put in vinegar and beaker
beakers are not made of water, they are made of glass.
