What else can I help you with?
Why did the water rise in the beaker When the candle burned out?
The water rose in the beaker because as the candle burned, it consumed oxygen in the air inside the beaker. This created a partial vacuum, causing the water to be pushed up into the beaker due to the air pressure outside.
What would happen to the water levels in the two beakers if you added an equal amount of salt to the beaker on the left?
If you add an equal amount of salt to the beaker on the left, the water level in that beaker will rise slightly due to the displacement caused by the added salt. In contrast, the water level in the beaker on the right, which has no added salt, will remain unchanged. The overall increase in water level in the left beaker is a result of the combined volume of the water and the salt.
What changes occur as you slowly heat a beaker of ice?
As you heat a beaker of ice, the ice will begin to melt and turn into liquid water. The temperature will slowly rise until it reaches a point where all the ice has melted. After that, the temperature will continue to rise as the liquid water heats up.
Why can water be poured in a beaker until it nearly overfills the brim?
Surface tension of water allows it to rise slightly above the brim without spilling over due to cohesion and adhesion forces between water molecules and the container. These forces create a concave meniscus which prevents water from easily overflowing the beaker.
What happened inside a beaker and on the bottom of the glass cover after you heated the water in the beaker?
Inside the beaker, the water absorbed heat energy, causing its temperature to rise and eventually boil. The steam formed from the boiling water then condensed on the cooler glass cover, forming water droplets on the bottom due to the temperature difference between the inside and outside surfaces.
How do you f ind volume of an object using water displacement method?
Fill a market beaker to a specific measured volume. (Eg. 50cm cubed, make sure you have not filled the beaker with water). Now place the object in the beaker with water. The water level should rise (Eg. from 50cm cubed to 60cm cubed). The difference in the original volume and the final volume is the volume of the object. That is the water displacement method.
If you pour germinating peas in a beaker and boiled peas in another in which beaker will the temperature rise?
The temperature will rise in the beaker containing the germinating peas due to the metabolic processes of germination producing heat. The boiled peas do not have living metabolic activity, so they will not generate heat in the same way.
How can you prove that air is a mixture?
Stand a large beaker full of air upside down over a container filled with lime water which has a lit candle (tea light, night light) floating on its surface. The flame from the candle will burn off the oxygen in the air which will cause the water to rise within the beaker. The water won't rise right up to the top which proves that their are other substances besides Oxygen in the air. And before you say that it is just the Carbon dioxide which has been produced by the burning of Oxygen, that is why Lime water was used. Lime water absorbs Carbon dioxide. So, whatever remains in the beaker is neither Oxygen or Carbon dioxide.
What happends to the water when heat is applied to the beaker?
If you left water in an open container for several days in summer, the water would eventually evaporate and there would be less water than you put before but if you put in in winter, the water would eventually freeze.
What method is to find the volume of a irregularly shape?
Depending on the size of the object this can be difficult. For a large object, lime a mountain, say, you have no option but to estimate. For smaller objects use a large beaker, and fill it with a liquid in which your shape is not soluble. Measure the volume of liquid in the beaker. Then place the object into the water and make sure it is totally submerged. The volume of the water in the beaker will rise and the volume of the shape is the difference between the two measures.
What happens to mercury in a beaker heats up?
As mercury heats up in a beaker, it will expand due to the increase in temperature. This expansion can cause the level of the mercury in the beaker to rise, potentially overflowing if the volume increases significantly. Additionally, as the temperature continues to rise, the mercury may vaporize and release potentially harmful fumes into the air.
Do liquids expand?
Yes. liquids expand. If we heat the beaker which is filled with water using a candle, the volume will rise as the water is mixed with hot air. Hot air would want to excape, therefore liquids do expand.
