How do properties, such as Density, help us to classify and identify matter?

Chemistry
1 answer:
kumpel [21]3 years ago

Density can be defined in terms of the mass of a substance present in a certain volume.

i.e. Density = Mass/ volume

It helps classify and identify matter due to the following reasons:

1) Density is an intensive property. For a given substance the density will remain the same irrespective of the amount in which it is present.

For example: The density of Aluminum (Al) = 2.7 g/cm3. This value is a constant at a certain temperature and pressure. Therefore, the density will remain the same for 1 kilogram or 1 mg of Al

2) Different elements/compounds have different values of densities which is characteristic of that substance

The option that would be appropriate to model nuclear fission is disturbing a drop of water such that it breaks into smaller droplets

Nuclear fission refers to the splitting of a heavy nucleus into lighter nuclei owing to the bombardment of small particle.

The liquid drop model provides the most apt model for describing the concept of nuclear fission. In nuclear fission, the nucleus breaks due to the increase in repulsion between the nuclear charges.

As the size of the nucleus continues to increase, any little disruption will; result in the breaking up of the nucleus into smaller fragment called daughter nuclei.

Hence, the model of disturbing a drop of water such that it breaks into smaller droplets is the most apt description of nuclear fission.

Cuando un gas que se encuentra a 20°c se calienta hasta los 40°c sin que varie su presion, su volumen se duplica
kati45 [8]

Answer:

Not doubled

Explanation:

The equation below represent the ideal gases relationship

PV ÷ T = constant

Here

P denotes pressure,

V denotes volume,

T denotes temperature in degrees Kelvin

Now

20 ° c = 273 + 20

= 293 K

And,

40 ° c = 313 K

So,

V = Vo. 313 K ÷  293 K = 1.07 Vo

So,  the volume is NOT doubled.

In the case when the temperature would be determined in degrees celsius at 0 degrees so the volume would be zero
