Answer:
Explanation:
Hello,
In this case, we can use the Avogadro's law in order to understand the mole-volume behavior as a directly proportional relationship:
Nonetheless, here we are not given neither the identity of the gas nor its molar or atomic mass, for that reason we can apply the aforementioned equation in terms of mass as we are talking about the same gas:
In such a way, the new volume turns out:
Best regards.
Max Planck was studying the emission of light by
hot objects. He believed that the hot objects did not emit energy continuously,
as would be expected if it were in the form of waves. Instead he suggested that
the object emits the energy in small, specific amounts called quanta. A quantum
is the minimum quantity of energy that can be lost or gained by an atom. He
proposed the following relationship between a quantum of energy and the
frequency of the radiation: E = hn.
E represents the energy in joules of a quantum of radiation, n<span> is the frequency of the radiation emitted, and
h is a constant known as Planck’s constant. Albert Einstein introduced the idea
that electromagnetic radiation has a dual wave-particle nature. Example: white
light exhibits many wavelike particles, it can also be thought of as a stream
of particles. Each particle of light carries a quantum of energy. He called
these particles photons. A photon is a particle of electromagnetic radiation
having zero rest mass and carrying a quantum of energy.</span>
