Answer:
Electrons can jump from energy level to energy level (for example energy level 1 to 2) but they can NEVER be found in between energy levels.
Answer:
Son aquellas características que comparte absolutamente toda la materia, sin distinción de su composición, forma, presentación o elementos constitutivos. Las propiedades generales no permiten diferenciar una sustancia de otra. Algunas propiedades extrínsecas son la masa, el volumen, el peso y la temperatura
Explanation:

Explanation:
It is known that relation between heat energy and temperature change is as follows.
Q =
where, q = heat energy
m = mass of the solution or solvent
= change in temperature
Hence, putting the given values into the above formula as follows.
Q =
=
= 34650 J
Now, calculate the energy of photons at wavelength 3.02 mm as follows.
E =
where, h = planks constant =
c = velocity of light = m/s
= wavelength = 3.02 mm = m (as 1 m = 1000 mm)
Therefore, putting the given values into the above formula as follows.
E =
=
= J
Now, the number of photons required of energy J/photon for the total energy of 34650 J as follows.
n =
=
= photons
or, = photons
Thus, we can conclude that the minimum number of photons present are .
