What is the ratio of mass and volume?
The ratio of mass to volume is called density.
Mass plus volume equals?
Time squared over distance. No, it is not "Density". Density is mass divided by VOLUME. Weight is the force of gravity acting on the mass. force = mass * acceleration. Thus, mass/force = 1/acceleration, or, in generic units, time squared over distance. Don't believe every game show answer you hear.
How and why would you use a beaker to measure the density of an object?
A beaker filled with liquid can be used to measure the volume of a non-soluble solid, or of a liquid. If the mass of the solid or liquid sample has been previously determined, the liquid (usually water) displaced from a filled beaker will provide the volume of the sample. Mass divided by volume gives the density. One of the early uses of the process was to identify counterfeit gold coins. In order to weigh the same as real gold coins, fakes would have to be thicker, and therefore have greater volume.
An irregularly shaped gold nugget weighs 24.3g and is found to displace 1.26ml of water. Can it be determined if it is really gold?
You can make a fairly good guess. What the first part of the experiment is designed to do is find the volume of the irregularly shaped nugget. Archimedes is the first to be recorded as offering this solution to finding the volume of an irregularly shaped object. By submerging the object in water, the experimenter can determine the volume of water the object displaces. By knowing the weight of the nugget and the volume of the nugget, and by comparing that to the known density of gold, you can make a fairly good guess as to whether or not it is gold. Let's look. Your nugget displaced 1.26 ml of water. That's 1.26 cubic centimeters of water. The nugget weighs 24.3 grams. Your nugget weighs 24.3 grams per 1.26 cubic centimeters. Divide this out to find the weight per 1 cubic centimeter: 24.3 grams / 1.26 cc = 19.29 grams per cubic centimeter. The density of gold, its weight per unit of volume, can be looked up with ease. As the known density of your nugget is about 19.3 grams per cubic centimeter, which is the known density of gold, there is a strong case for your nugget to be gold.
What kind of substance has a definite shape but no definite volume?
volume= mass\Density . so as if shape remain same then its mass and density remain fixed . so therefore no such object , but if we apply Einstein theory of relativity then as it says " after traveling some distance each object looses its mass which is very less i.e in fraction, which in negligible . Therefore each object is the answer.
The amount of mass an object has per its volume is known as .?
Density = Mass/Volume
What is the formula for calculating density if the mass and volume of an object are known?
The object's density = (its mass) divided by (its volume)
How the density of a regular and irregular objects determined?
Weigh the object. Determine the volume. Divide the mass by the volume to get the density. To get the volume of an irregular shaped object can be challenging especially if there are cavities (holes) in it. submersion in a liquid or powder of known volume might be possible. Measure the difference in the volume of the liquid and the liquid + the object (making sure the object is entirely below the surface of the liquid and that any cavities are filled).
How can you find the mass of an object if the volume is known but not the density?
Without knowing either the mass of an object or its density, it would be impossible to find the mass. There would be two variables and only one equation. Thus, one cannot find the mass of an object solely from its volume.
How can you find the mass of an object if the volume of the object and the density of the liquid is known?
The law of conservation of mass states mass= density times volumeThe definition of density=mass/volumemultiply the density and the volume! =mass
What other variable needs to be defined to calculate the weight of an object if the volume is given?
To calculate the weight of an object when the volume is known, you would also need the density of the material the object is made of. By multiplying the volume of the object by its density, you can determine the weight of the object.
How can you measure the density of non uniform object.?
it can be measured if the mass of the object is known,,by imerging it into a known density and volume of liquid-like substance like water, now measure the displacement which give clue on it uniform volume. Then divide its mass by its volume. The result is now the the density of the non uniform object.
What devices can you use to find the volume and density of substances?
volume: put the object into a known volume of water and measure the difference (achrimedes) for density divide the volume by the weight
What is the density of an object that has a mass of 30 grams?
In physics the density (ρ) of a body is the ratio of its mass (m) to its volume (V), a measure of how tightly the matter within it is packed. So in order to answer your question, the volume of the object must be known. If the volume is known, simply divide its mass with its volume. Also pay attention to what units are used to express mass and volume and present them in your answer. For example, if the mass is in grams and the volume is in cubic centimers, the number in your answer will have the unit grams per cubic centimeter.
How do you identify an object using density?
To identify an object using density, you would need to measure its mass using a balance and its volume using displacement or geometric methods. Then, calculate the density of the object by dividing the mass by the volume. Compare the calculated density to known densities of materials to determine the identity of the object.
What is the amount of mass of an object compared to its volume?
Mass is the amount of matter in an object. It is not the same as weight, and cannot be calculated in the same way. To figure out the mass in a given volume, multiple the volume times the density.
What are 2 ways to find the volume of an object?
Derive from measurements of length, breadth, height, radius, diameter etc. Measure the volume of displaced liquid when the object is submerged. If the object is of a material of known density (or specific gravity), weigh it and calculate volume from volume = mass/density.
