Correlation between size and mass of particles

In summary, the conversation discusses whether there is a correlation between the size of a matter particle and its mass, specifically in relation to its matter wavelength. While the de Broglie wavelength formula can provide an indirect sense of the particle's size, it is not a definitive measure as elementary particles are considered to be point-like. The conversation also addresses the difference between de Broglie wavelength and momentum and the OP's attempt to change the focus of the original question.

Is there a correlation between the size of a matter particle (defined as its matter wavelength) and the mass of the particle? With the photon, its wavelength and its energy/mass are inversely correlated. Is it also true of matter particles?

And what do you mean by "matter wavelength" and why should it be considered as particles size? If it's de Broglie wavelength then just check the formula for it.

de Broglie wavelength depends on the momentum of the particle, not its mass.

How else to consider particle size?

Well, elementary particles (like electron) are considered to be point-like, that is, they don't have size.

Since de Broglie wavelength = h/momentum = mass x velocity, that would give us an indirect sense of the ‘size‘ of the particle, in relation to its mass.

How?

de Broglie wavelength = momentum

Nope, that's not the formula, but you're close.

Thgis started out as a question with a simple answer - "there isn't one". Why are you (the OP) trying to morph this qu4estion into one with a different answer?

1. What is the relationship between the size and mass of particles?

The size and mass of particles have a direct correlation, meaning that as the size of a particle increases, its mass also increases. This is because the larger the particle, the more atoms or molecules it contains, resulting in a higher mass.

2. How does the correlation between size and mass of particles affect their behavior?

The correlation between size and mass of particles can affect their behavior in various ways. For example, larger particles tend to have a higher gravitational force, making them more likely to settle at the bottom of a mixture. Additionally, the size and mass of particles can affect their ability to dissolve or react with other substances.

3. Can the correlation between size and mass of particles be used to determine the properties of a substance?

Yes, the correlation between size and mass of particles can provide valuable information about the properties of a substance. By measuring the size and mass of particles, scientists can determine the density, melting point, and other physical characteristics of a substance.

4. Are there any exceptions to the correlation between size and mass of particles?

While the correlation between size and mass of particles is generally true, there can be exceptions. For example, in some cases, the size of a particle may increase while its mass remains constant due to changes in its structure or composition.

5. How is the correlation between size and mass of particles relevant in different fields of science?

The correlation between size and mass of particles is relevant in various fields of science, such as chemistry, physics, and materials science. It is essential for understanding the properties and behaviors of substances, as well as for developing new materials and technologies.
