What else can I help you with?
Why do you have to wet the stone before dropping it into the graduated cylinder?
If you were to drop a dry stone into a graduated cylinder it would pull a lot of air bubbles down with it (they stick to the surface, you should actually be able to see them) and that will give you an erroneous volume.
What are bubbles composed of while boiling?
Bubbles are composed of water vapor while boiling. As the liquid heats up, it turns into steam and creates bubbles that rise to the surface. The bubbles then burst, releasing steam into the air.
What is a measuring cylinder used to for?
A graduated cylinder is used to measure the volume of a liquid and occasionally a solid (it can be inverted and used to measure gas as well!) The cylinder is made of glass (usually Pyrex) or plastic and has measured lines with volume values noted on the lines (a.k.a. graduations.) Simply fill the cylinder with a liquid until it reaches the volume you require. When measuring the liquid level you will notice that electrostatic forces and gravity alter the shape of the liquid's surface to a crescent shape. This is called a "meniscus." In most cases the shape will look like a smile, you must make the measurement so the bottom portion of the smile shape is lined up with the graduation mark on the cylinder. Occasionally the meniscus will be close to flat or inverted like a frown, such is the case with liquid mercury. In such scenarios, the uppermost portion of the frown shape should be used for accurate measurement. To measure the volume of a small solid object of irregular shape, you can measure out a certain volume of a liquid (like water) in the cylinder, and then carefully place the solid objects in the cylinder, making sure they are completely submerged and contain no air bubbles. The water is displaced to a new reading on the graduated cylinder and the difference between the original and the final readings is the volume that the solid object occupies. Measuring the volume of a gas is more complicated to set up and explain. In general the graduated cylinder is filled with liquid and inverted in a large container filled with water. The gas reaction evolves gas through a tube, directly under the inverted cylinder, and rises to the top (the base of the inverted cylinder). The amount of gas produced will displace the water downward as it fills the top of the cylinder and can be measured using the graduations when the gas has ceased. This will give you the volume that the gas occupies. If the gas is soluble in the liquid, some may remain dissolved and give a false-low volume reading.
What forms when water slowly bubbles underground?
When water slowly bubbles underground, it can form geysers or hot springs. Geysers erupt intermittently, releasing steam and water into the air, while hot springs have a constant flow of warm water to the surface. Both are caused by underground volcanic activity or geothermal heating.
Why does bubble wrap pop when you squeeze it?
Bubble wrap pops when you squeeze it because the air pockets inside the bubbles are forced to escape through the material, creating a popping sound. The pressure exerted when squeezing the bubble wrap causes the bubbles to burst, releasing the air trapped inside them.
Why should you tilt the graduated cylinder when you drop in objects?
Tilting the graduated cylinder allows the object to slide down gently without splashing or bouncing. This helps to prevent the formation of air bubbles that could affect volume measurements.
Why do you have to wet the stone before dropping it into the graduated cylinder?
If you were to drop a dry stone into a graduated cylinder it would pull a lot of air bubbles down with it (they stick to the surface, you should actually be able to see them) and that will give you an erroneous volume.
How do you read a graduated cylindar with urine?
To read a graduated cylinder with urine, place the cylinder on a flat surface at eye level, ensuring the liquid is not spilling or forming bubbles. Read the measurement at the bottom of the meniscus, the curved surface of the liquid. Take note of the volume marking that aligns with the bottom of the meniscus for an accurate reading.
11.85 grams of aluminum fragments are placed into 50 ml of water in a graduated cylinder Where will the water line appear on the graduated cylinder knowing that the mass of aluminum is 26.98?
11.85 cannot equal 26.98.Rephrase your question (perhaps you mean that the densityof aluminum is 2,698?)Is all the air evacuated? (no bubbles left attached to the aluminum fragments?)
How do goldfish make bubbles underwater?
Goldfish make bubbles underwater by releasing air from their gills, which creates bubbles that rise to the surface of the water.
What is the bubble ontop of a graduated cylinder?
The bubbles on top of a drink are just air bubbles. When carbonated beverages are poured into a glass they form an area on top of the drink that looks like foam. The slang word for this is suds or a head.
What are bubbles composed of while boiling?
Bubbles are composed of water vapor while boiling. As the liquid heats up, it turns into steam and creates bubbles that rise to the surface. The bubbles then burst, releasing steam into the air.
What is the scientific name of bubbles?
I need help on that too im doing a metrics challenge sheet I need help on that too im doing a metrics challenge sheet The bubble in the middle of a graduated cylinder is called a miniscus. I must be doing the same sheet. :)
How do goldfish make bubbles on the surface of the water?
Goldfish make bubbles on the surface of the water by releasing air from their swim bladders through their mouths. This process is called "gulp breathing."
How should you use a graduated cylinder?
Use the smallest volume graduated cylinder capable of holding the liquid to measure, this will result in the most accurate result. First, to insure greatest accuracy, one should make sure conditions are appropriate for the use of the cylinder, meaning that most graduated cylinders are calibrated for use with water at 20 degrees Celsius. One can determine this by looking for "20° TC" or "20° TD" marked on the cylinder. "TC", or "to contain", means that the volume of liquid contained in the cylinder is what is indicated by the graduated markings. "TD", or "to deliver", means the volume of liquid indicated by the markings is what will be delivered when the liquid is dispensed. This difference exists because when liquid is dispensed from any glassware a small amount remains and "TD" takes this difference into account. Second, the liquid should be poured into the cylinder carefully down one side, tilting the cylinder to minimize splashing and the formation of bubbles. Finally, to read the liquid volume, the cylinder should be on a level surface and the liquid level read at the bottom of the meniscus at eye level.
How can you determine the volume of a arrowhead?
Put the arrowhead in a beaker or graduated cylinder containing a known amount of water. Tap the arrowhead to dislodge any stray air bubbles. Note the displacement caused by the arrowhead. That is the arrowhead's volume.
Why won't the brake cylinder compress properly?
The brake cylinder may not compress properly due to air bubbles in the brake fluid, a leak in the brake system, or a malfunctioning brake cylinder.
