A scale, a beaker and a graduated cylinder. You use the scale to determine the mass of the object. If it is a solid, you can just place it on the scale. If it is a liquid you have to keep it in a graduated cylinder or beaker and weigh it. But remember to subtract the weight of the beaker/graduated cylinder. Then you have to find the volume. For a liquid, this is very easy. Just put it into a graduated cylinder and read the ml on the side. If it's a solid, then there are two ways to do it. If it is a very even shape, such as a cube or a cylinder etc, you can take precise measurements and use the volume equations available for the certain shape. Another way is to do water displacement. Put water into the beaker and record the volume. Then put the solid in the water (make sure the solid doesn't dissolve in water first). Record the volume and subtract the original volume. The density is just mass divided by volume.
density = mass/volume → The density of the rock is the mass of the rock divided by the difference in the volume from before the rock was dropped in and afterwards. Its units are grams/ml
well, there's two ways we can manage that, first we can measure it's dimensions and calculate this. because of the multiple equations needed for determining it this way I have another method you could use, if you have enough needles the same size. in a small graduated cylinder place 20 ml of water put as many needles of the same size in the cylinder as you can read the change in volume on the cylinder divide the change in volume by the number of needles this is the volume of one needle
To make 15% alcohol from 40% alcohol you simply take 15cc of your 40% alcohol and put it into a graduated cylinder and fill the cylinder up the rest of the way with deionised water or distilled water to the 40cc mark on the graduated cylinder. you will then have 15% alcohol from 40%
Water displacement is simply when something (e.g. a block) is put into water, and the water level rises. This is because the block is taking up space, and the water has to move somewhere, and the only place to go is up.
You can put water in the graduated cylinder and drop the solid in and see how much the water rises
As many as were put into it, subject to the total capacity of the cylinder.
Fill the graduated cylinder with water, and measure the volume. Now put the item in, measure the water's volume again, and take the difference
To find the volume of water you must put it in a graduated cylinder. Read the measurements.
Put it in a graduated cylinder. a) Find a graduated cylinder big enough to hold a can of Coke. b) Make sure it has a small scale. (Smaller scales are more accurate.) c) Fill the graduated cylinder with water to a mark on the cylinder. d) Find how much higher the water is when you drop the can in.
It is a problem of surface tension of water and contact angle between water and glass (or a plastic).
Anything that is small enough.
length x width x height or put water in a graduated cylinder, and measure the volume of water. then place the object in the graduated cylinder and record the new volume of the water. subtract the old volume from the new, and that is the volume of the object.
If the object in question is water proof, and small enough. You can measure the amount of displaced water when it is placed in a tank full of water, this may not work for a lot of things but it can help when attempting to measure some objects.
A graduated cylinder consists of glass. Glass is a highly polar substance. Mercury is nonpolar and has no significant attraction to glass, but mercury atoms are attracted to one another by metallic bonding. Therefore, mercury will form an upward-curving meniscus in a glass buret.
The fact that they are waterproof. Partly but they take space in the water and as a result water is displaced and rises.
Yes you can. You put liquid (usually water) in the graduated cylinder. Then record how much liquid you put in it. Next, put the object in the graduated cylinder. Look at where the water level is now. Take that number and subtract the amount of water you put in and that should give you the approximate volume of the object.
