How measuring The mass of a solid is different from measuring the mass of a liquid Explain?
Measuring the mass of a solid involves using a balance scale to weigh the solid directly, while measuring the mass of a liquid typically involves using a container to hold the liquid and then weighing the container with the liquid inside. Liquids can take the shape of their container, so the mass of the container needs to be accounted for in the measurement.
Explain the method of determining the density of urine using urinometer?
To determine the density of urine using a urinometer, you simply place the urinometer in a container of urine and allow it to float. The reading is taken at the point where the surface of the urine intersects with the scale on the urinometer. The density of the urine is then determined by comparing this reading to a known scale.
Explain how a hydraulic lift operates?
A hydraulic lift operates by using a system of fluid-filled cylinders to raise or lower a platform. When force is applied to a smaller cylinder filled with fluid, it creates pressure that is transmitted through the fluid to a larger cylinder, resulting in the lifting or lowering of the platform.
What does graduated equilibrium mean?
Graduated equilibrium is a concept in biology where species show a gradual change in form or function over a geographic range, forming a continuum of traits. This gradual change allows for adaptation to different local environments while maintaining enough genetic connectivity between populations. It helps to explain how species can diversify and adapt to various habitats over time.
How do you Explain acoustic how microscope works?
An acoustic microscope uses sound waves to produce high-resolution images of a material's internal structure by measuring variations in acoustic properties. The sound waves are focused on the material and the resulting echoes are analyzed to generate an image. This allows for non-destructive imaging of features that may not be visible with optical microscopes.
Explain Why is the surface of water in a graduated cylinder curved?
it is probably called figure it out, it is curved because glass is sticky. When you measure the volume from a graduated cylinder, measure at the bottom of it. It is called the meniscus.
On a hot day a student observes water drops on the outside of a bottle of cold water. Explain this observation in terms of the concept of thermal energy.?
Use the water displacement method. You need a graduated cylinder and some water. Fill the graduated cylinder with enough water so that when you place the rock in the graduated cylinder it will cover the rock. Read the meniscus (the slightly curved line of the water) at eye level. Record your measurement of the water in the graduated cylinder (in mL). Place the rock in the graduated cylinder and record your new measurement of the water line, again at eye level. Subtract the original measurement from the new one to get the volume of the rock.
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.
Explain the different processes in measuring the volume of a liquid and measuring the volume of a rectangular solid.?
You can measure the volume of a liquid by pouring it into a container with scale markings - measuring cup or graduated cylinder. The volume of a solid shape can be calculated by a geometric formula. If the shape is irregular, the volume can be found by displacement of a liquid. See the related link for a famous story!
What is the smallest graduated cylinder you can buy?
The smallest grad cylinder I have ever personally seen was 10 mL, and that's the smallest size that's readily commercially available (if you're willing to spend the money, one of the custom glassblowing supply companies would probably make you one of any size you wanted). For smaller amounts, though, (and approximately the same level of precision), a graduated pipette is usually used instead.
How can you explain a cylinder to someone who has never seen one?
a cylinder is like a can
Explain how you find the volume of a marble using displacement?
You take a graduated cylinder,or anything you can measure water in, and put water in it. You drop the marble in and the change in water height is your volume. For example if the cylinder is filled up to 10ml and after you drop in the marble it goes to 15ml then the marble has a volume of 5ml cubed.
If you have been asked to accurately measure out 50 cubic centimetre of a liquid experimentwhich piece of glassware wouls you use explain and justify your answer?
A 50ml fixed volume pipette. Graduated pipettes are less accurate, multiple pipettes are bad for accuracy, and most other glassware is bad for accuracy. Also look for the highest class pipette available
Explain How the process of measuring a liquid's volume differs from the process of measuring a solid volume?
the size of its head
Explain whether or not a cylinder has to have a circular base?
a cylinder has to have a circular base because it is a circular prism
Explain the purpose and function of cylinder block?
Housing the cylinder and the components inside a cooled and lubricated crankcase
To explain one method that might be used to determine the density of a solid material and one method that might be used to determine the density of a liquid?
One method to determine the density of a solid material is to measure its mass using a balance and then measure its volume using a graduated cylinder or displacement method. Divide the mass by the volume to find the density. For a liquid, one method is to measure its mass using a balance and then measure its volume by using a graduated cylinder or a specific gravity bottle. Divide the mass by the volume to calculate the density.
