Polylactic acid is the correct answer
The energy range expected is 6.6 × 10^-19 J < E < 7.33 × 10^-19 J
The energy of the photon is given by;
E = hc/λ
E = energy of the photon
h = Plank's constant
c = speed of light
λ = wavelength of light
For the upper boundary range;
E = ?
h = 6.6 × 10^-34 Js
c = 3 × 10^8 m/s
λ = 270 × 10^-9
E = 6.6 × 10^-34 Js × 3 × 10^8 m/s / 270 × 10^-9
E = 7.33 × 10^-19 J
For the lower range;
E = ?
h = 6.6 × 10^-34 Js
c = 3 × 10^8 m/s
λ =300 × 10^-9
E = 6.6 × 10^-34 Js × 3 × 10^8 m/s / 300 × 10^-9
E = 6.6 × 10^-19 J
Hence, the energy range 6.6 × 10^-19 J < E < 7.33 × 10^-19 J

Answer : Electron P has greater energy difference than the Electron N.
Explanation :
Wavelength range of violet light = 400 - 500 nm
Wavelength range of orange light = 600 - 700 nm
The Planck's equation is,
![E=\frac{h\times c}{\lambda}](https://tex.z-dn.net/?f=E%3D%5Cfrac%7Bh%5Ctimes%20c%7D%7B%5Clambda%7D)
where,
E = energy of light
c = speed of light
= wavelength of light
According to the Planck's equation, wavelength and energy follow inverse relation. As the wavelength increases, energy decreases.
From the given spectrum, the wavelength of violet light is less. We conclude that When electron P gives violet light on transition it means that energy difference between the energy level was high.
From the given spectrum, the wavelength of orange light is more. We conclude that When electron N gives orange light on transition it means that energy difference between the energy level was low.
So, Electron P which gives violet light on transition has greater energy difference than the Electron N.
<h2>Hello!</h2>
The answer is: 4.77atm
<h2>Why?</h2>
Since there's a fixed volume, we can use the the Gay-Lussac's Law which stablish a relation between the pressure and the temperature:
![\frac{P}{T}=k](https://tex.z-dn.net/?f=%5Cfrac%7BP%7D%7BT%7D%3Dk)
<em>P</em> is the volume of the gas
<em>t</em> is the temperature of the gas
<em>k </em>is the proportionality constant
We also have the following equation:
![\frac{P1}{T1}=\frac{P2}{T2}](https://tex.z-dn.net/?f=%5Cfrac%7BP1%7D%7BT1%7D%3D%5Cfrac%7BP2%7D%7BT2%7D)
Where:
![P2=\frac{P1*T2}{T1}=\frac{317kPa*235K}{154K}=483.73kPa](https://tex.z-dn.net/?f=P2%3D%5Cfrac%7BP1%2AT2%7D%7BT1%7D%3D%5Cfrac%7B317kPa%2A235K%7D%7B154K%7D%3D483.73kPa)
We are asked to find the pressure in atm, so we must convert 483.73kPa to atm:
![1kPa=0.009869atm](https://tex.z-dn.net/?f=1kPa%3D0.009869atm)
Then,
![483.733kPa*\frac{0.009869atm}{1kPa}=4.77atm](https://tex.z-dn.net/?f=483.733kPa%2A%5Cfrac%7B0.009869atm%7D%7B1kPa%7D%3D4.77atm)
Have a nice day!
