It can be easy to measure one part bleach to ten parts water. Simply search for a cup or container and fill it once with bleach. Dump this bleach into a larger container and measure out ten of the same cup's worth into the container with the bleach.
Water displacement method will work fine with molecules that do not dissolve... Here you have something that will dissolve in water, changing it's density. What I would do is to weight a graduated container, put some sugar (more you add, more precise will be the result) in the container... Better weight the container before... Weight the container after. Now you know the *weight* part of the answer, then you melt it, in that container... you read the *volume* part of the answer. put the part together to have a density which is mass/volume g/cm³ for example, or g/mL, which is the same.
immerse the frostbitten part in a container that has luke warm water
You need to measure the mass using appropriate equipment. You can measure the volume of a textbook and a container of milk by measuring its linear dimensions and calculating the volume. It is not at all easy to measure the volume of an air balloon. You cannot use displacement of a fluid (water) because when submerged, the balloon would be experiencing water pressure and so would occupy a smaller volume. You cannot measure it by allowing the air to escape and measure that volume of air because that air will no longer be experiencing the pressure exerted by the material (rubber?) of the balloon. I have no answer to this part. Once you have the mass and volume, the density is merely mass/volume.
You should always measure at the lowest part of the meniscus. The meniscus is a slight curvature at the top of a liquid in a container.
The water disappears from an open container placed in the sun due to evaporation. The sun's heat causes the water molecules to gain energy and change from liquid to vapor, rising into the air and becoming part of the atmosphere. This process continues until all the water has evaporated.
Answer: The process is more like removing the water from the salt water as the salt stays just where it started out.The salt water is placed in a closed container and allowed to get warm in the sun (it doesn't have to boil.) The warm water evaporates out of the solution into the air over the solution.Now for the secret, there has to be a colder part in the container like a glass of cold salt water where the water vapor can condense on the outside and drip down into a receiving container. This water is salt free. Solar stills of this nature are available commercially and are often part of the survival gear on lifeboats.
By filling the container 3/4 full at a time. Get a (one pint) 16 oz container--or one up to 5.33 ounces larger--and use it for your measuring cup.
Only if the beaker is very full and the surface is rounded. Otherwise, the cork will float to the edge of the container (which is typically the highest part of the water).
Then the substance in the container becomesa mixture of hot dirt in hot water.
the water will be stored in a closed container and electrolysis of water will be done ,then hydrogen will be used as fuel which will combine with oxygen to form water which can further be used the same way and so on !! the difficult part is the easy way for electrolysis of water
