How can you separate substances of different densities?
Density Column to Separate Mixtures of SolidsYou could use a density column to separate mixtures of different solids by adding substances that have different densities. Then you would add in the solids, which would land or stop at a substance.
Does water sink or float?
does water sink or float in what? whether one solution "floats" or "sinks" when added to a 2nd solution depends largely on the relative densities of the two solutions. Generally the denser of the two will "sink", though other factors, such as polarity, come into play in certain situations (eg, mixing oil and alcohol).
20 kilos flour to litres?
There can be no conversion.A kilogram is a measure of mass. A litre is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.The masses of equal volumes of the two substances will clearly be very different. So there is no direct conversion between mass and volume: you need to know the density of the substance to enable you to carry out the conversion. Flours from different grains have different densities.
What is the difference between two things?
The difference between two things is what traits or characteristics set them apart; why they are different. For example:Water and IceThe difference between water and ice is that water is a liquid and water is not. Another thing is that ice is very cold and water can be warm.
Does the mass of water decrease when salt is added?
Because the formula for density=Mass/Volume, so since density of water is always constant, when the volume (the amount of water) increases, then the mass (in grams) will also increase to make sure the density # is the same. Mass and Volume are directly proportional. when one goes up, the other goes up, and vice versa.
Why aren't cooking oil and water miscible?
They have different densities, water being the heaviest of the two, so they do not mix.
Can two object have the same volume but different densities?
No,because if they have the same volume,that also means they need to have the same densities. > Density = mass / volume. Say they are different materials, such as water and iron. With an equal volume of both, the iron would be 7.85 times the weight. Therefore iron has 7.85 times the density of water.
Why can two objects with the same mass have different densities?
Volume. Density depends on mass and volume. Density = mass/volume. Things that have the exact same mass can have different densities if the volume associated with either are different.
How can 2 objects have the same volume but different densities?
Two objects can have the same volume but different densities if they have different masses. Density is calculated as mass divided by volume, so if the masses of the two objects are different even though their volumes are the same, their densities will also be different.
If two solids have the same masses but different volumes they have?
different densities. Density is defined as mass divided by volume, so if two solids have the same mass but different volumes, their densities will be different. The solid with the smaller volume will have a higher density, while the solid with the larger volume will have a lower density.
How can the volume of two substances be the same but the mass be different?
They have different densities.
Can two objects with the same volume have different masses if so why?
Yes, two objects with the same volume can have different masses if they are made of materials with different densities. Density is the mass of an object per unit volume, so objects of the same volume but different densities will have different masses.
If two solids have the same masses and different volumes do they have different or equal densities?
different equal
Is it possible for two objects to have the same volume and different densities?
Yes, it is possible for two objects to have the same volume but different densities. Density is a measure of how much mass is contained in a given volume, so two objects with the same volume but different masses will have different densities. For example, one object could be made of a denser material than the other.
Why two different liquids could haved ifferent densities?
They can be made of different atoms, different masses of the atoms, different sizes of the atoms. Mercury atoms are very small, and very heavy. Bromine atoms are larger and lighter. For molecular substance another factor becomes important. Who well the molecules fit together, How much empty space is still there between the molecules because of how the can pack together. Water molecules pack very well together. Gasoline molecules do not pack as well. The molecules of gasoline are larger and more complex, but the density is less than water because of how much better water molecules pack together.
How can two items have the same shape and size have different densities?
It doesn't have the same density because the two items can be different masses.
What is a mixture that separates into layers?
An example of a mixture that separates into layers is oil and water. These two substances do not mix well and will form distinct layers due to their different densities. This separation is due to the immiscibility of the two substances.
