The water curves in a graduated cylinder due to a phenomenon called capillary action, which is influenced by the adhesive forces between the water molecules and the glass of the cylinder. Water molecules are attracted to the glass, causing the surface of the water to rise along the edges, creating a meniscus. This curvature is typically concave for water in glass containers. The shape of the meniscus is also affected by the balance between cohesive forces among water molecules and adhesive forces between the water and the cylinder.

What lab equipment is most useful in finding the denisty of an object?
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.
How would you measure the volume of a screw?
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
What is the volume of a metal cylinder weighing 18.03 grams if you put it in 15mL of water and it rises to 21.4 mL?
The increase in volume of the water when the cylinder is added is equal to the volume of the cylinder. So, the volume of the cylinder is 21.4 mL - 15 mL = 6.4 mL. Since the metal cylinder is immersed in water, the volume of the metal cylinder is 6.4 mL.
Does a graduated cylinders use millimeters?
A graduated cylinder is more accurate to measure by millilitres, definitely. Unless you are told where gradiations should start. The millilitre graduations (and often 0.1ml graduations) are calibrated properly. Whereas, if you were to put in millimetre calibrations you would end up with very imprecise volumes.
If you have a graduated cylinder that contains ml of water you drop a rock into the cylinder and the water level rises to ml the mass of the rock is grams what is the rocks density?
Well, darling, density is mass divided by volume, so in this case, the mass of the rock is grams and the volume of water displaced by the rock is ml. Just plug those numbers into the formula and you'll have the rock's density in g/ml. Easy peasy lemon squeezy!
How can you measure the volume of solid with a graduated cylinder?
You can put water in the graduated cylinder and drop the solid in and see how much the water rises
What can you put in a graduated cylinder?
You can put liquids such as water, oil, or alcohol in a graduated cylinder for measuring volume accurately. It is not recommended to put solid objects in a graduated cylinder because it can affect the accuracy of the measurement.
How many liters of water are in a graduated cylinder?
As many as were put into it, subject to the total capacity of the cylinder.
How do you measure a solid using a graduated 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
How is the volume of water found?
To find the volume of water you must put it in a graduated cylinder. Read the measurements.
What causes the water level rise when you put an object in a graduated cylinder?
When you put an object in a graduated cylinder, the water level rises because the object displaces water equal to its volume. This is known as Archimedes' principle. The increase in water level corresponds to the volume of the object that is submerged in the water.
How can you accurately find the volume of a can of Coke?
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.
Why does water have a meniscus if you put it inside a graduated cylinder?
It is a problem of surface tension of water and contact angle between water and glass (or a plastic).
Which property of water causes water to curve in a graduated cylinder?
With most liquids, the attractive force between the liquid and the container is greater than the attraction between the individual liquid molecules. So the liquid "sticks" to the side of the container. A few liquids have a "backwards" meniscus. An example is mercury. If you put mercury in a test tube, it would be higher in the middle than at the edges.
What are two different ways to measure volume?
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.
Why does the mercury curve upwards when put inside the graduated cylinder?
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.
How could you measure the volume of an object with an irregular shape?
One way to figure this out is to put the object in a graduated cylinder containing water and measuring the changes in the volume of the water.
