Why can water be poured in a beaker until it nearly overfills the brim?

because water is a liquid and liquids are easy to pour most of the time and that is what a beaker is for.

How can a liquid be transferred from a beaker to a funnel without running down the outside walls of the beaker?
There is a technique of pouring down a glass rod detailed here: a glass rod is held across the top of the beaker with one end sitting in the beaker's spout and extending approx. 2 to 3 inches beyond the wall of the beaker. The beaker is then tilted, slowly, with the rod pointing into the top of the funnel, until the liquid contents run along the rod and drip into the funnel.
Why do you need to add distilled water in a potassium iodate solution in a volumetric flask until it reaches 250ml?
To dilute it to a certain concentration given in moles. It is best to transfer it to a beaker first to make sure it dissolves. The 250ml figure is dependent on how much of the solution that you need
How can you separate a mixture of sand from water?
I would let the sand settle out of the mixture, then pour off the water, leaving the sand behind. If you needed to extract the remainder of the water, put the wet sand into a centrifuge and spin it until the water is out and collected from the centrifuge.If you want to separate sand from water take a beaker a pebble and a filter paper then fix the filter paper in the pebble and put it on the beaker and add the mixture of water and sand then the water will be in the beaker and the sand will be on filter paper. Remember use Steve for thick things such as tiny stones etc and apply the same method.
A student takes some water in a beaker and heats it over a flame for determining its boiling point He keeps on taking its temperature readings He would observe that the temperature of water?
Increases until it reaches 100 degrees Celsius, at which point it would begin to change phase into gas and stop increasing in temperature.
How can someone test the effect of heat and acids on milk proteins?
You can do this:Materials Needed:1. Skim milk, 125 mL 2. Beaker, 250 mL3. Vinegar (acetic acid), 25 mL 4. heat source5. Sodium bicarbonate (baking soda), 1g 6. Funnel and filter paper7. stirring rod 8. water, 30 mL9. Graduated cylinder, 125 mLStrategy:1. Place 125 mL of skim milk in a 250 mL beaker.2. Add 25 mL of vinegar, which is an acidic solution.3. Gently heat milk and stir constantly until small lumps begin to form.4. Remove beaker from heat and continue to stir until no more lumps form.5. Allow lumps to settle.6. Filter the solid (curds) from the liquid (whey) using funnel.7. Gently press the filter paper around the curds to squeeze out the excessliquid through the filter paper.8. Return the solid to the beaker9. Add 30 mL of water to the solid and stir10. Add 1/2 tsp. of baking soda to neutralize vinegar, bubbles should appear.Add a little more baking soda until no more bubbles appear.11. The substance in the beaker is glue. Test the adhesive properties,including waterproof property.I am doing this for a science experiment this year and it worked
What order do you put the chemicals in the beaker on big nate poptropica?
The blue beaker then the yellow beaker until green.
What happens when you fill a beaker of soil with water until the beaker is almost full?
You get a heavy beaker full of mud.
What is a rocks pour?
About a shot and a half or poured until the ice (rocks) is lifted.
How do you get 9 liters from a 10 and 7 liter beaker?
Fill the 7 beaker and pore contents into 10 beaker. Mark where the contents come up to on the 10 beaker. Fill the 10 beaker up and pour off the top of it into the 7 beaker until you are down to the mark. You will now have 3 litres in the 7 beaker. Mark where it comes up to. Empty the 10 beaker. Pour the 3 litres in the 7 litre beaker into the 10 litre beaker. Fill the 7 litre beaker up to the 3 litre mark and pore it into the 10 twice more. You now have 3*3=9 litres in the 10 litre beaker. QED.
Are leeches will die after sprayed by disinfectant?
No. Leaches are a disgusting animal that don't die until salt is poured on them.
WherE is the stink bomb in big nate island poptrapica?
Well, actually, you have to make the stink bomb. You go to the science lab and to the beaker with the test tubes nest to it. You click on the beaker and it will show up with three colors of liquid. you but the boiler that is underneath the beaker to 4, and add the colored liquids to the beaker. What you want to do is create a grayish green color with all of the colors mixed. Fill up the beaker with the colors, though, otherwise it won't work. So, you fill up the beaker with the colors until it is full and it has a grayish green color to it.

What instrument using for determination of concentration of salt water?
Measure out any volume of water in a pre-weighed beaker (or container...sigh*). Then bake the beaker in a warm oven until all the water evaporates and the beaker is dry. Reweigh the beaker . Subtract the original weight of the empty beaker from the new weight. You now have the weight of the salt present in your original amount of water ! NOTE: If you are using ocean water this may be imprecise due to other contaminants remaining in the beaker. AKA you are not JUST weighing salt at the end. SOURCE: I'm an Organic Chemistry teacher...it's what I do!
A small toy has a volume of 20 cm and a mass of 45g what is the density of the toy?
No way exists to answer your question. 20 cm is a unit of length. It is not a unit of volume. Knowing that your toy is 20 cm long and has a weight of 45 g does not provide enough information to give the density of the toy. Take your toy. Put it into a large beaker. Cover the toy with water. Put a mark on the side of the beaker at the waterline. Remove your toy. Put a mark at the top of the water line. Fill a graduated cylinder to the top line. Now, slowly pour water into the beaker until you raise the level of the water to the top line. Write down how much water you poured into the beaker. Now take that amount in ml and divide it into the number of g. If it is 22.5 ml and 45g your density is 2.
