Maybe because gravity has control of each formation of the solarsydtem thats why its just a guess
Answer: Transition from X to Y will have greater energy difference.
Explanation: For studying the energy difference, we require Planck's equation.
where, h = Planck's Constant
c = Speed of light
E = Energy
= Wavelength of particle
From the equation, it is visible that the energy and wavelength follow inverse relation which means that with low wavelength value, energy will be the highest and vice-versa.
As electron A falls from X-energy level to Y-energy level, it releases blue light which has low wavelength value (around 470 nm) which means that it has high energy.
Similarly, Electron B releases red light when it falls from Y-energy level to Z-energy level, which has high wavelength value (around 700 nm), giving it a low energy value.
Energy Difference between X-energy level and Y-energy level will be more.

Explanation:
The Ideal Gas Law states that PV=nRT.
Rearrange that into P/n=RT/V.
In this case, the cylinder is rigid so the volume, V, does not change.
Temperature does not change either.
Out of 450 grams of gas, 150 grams leak out. So only 450-150 = 300 grams is left.
n is number of moles which is dependent on mass:
n1/n2 = 450/300 = 3/2
P1/n1 = RT/V = P2/n2
P2 = P1/n1*n2
= 7.2/3*2
= 4.8 atmosphere

Explanation:
Coal is primarily used for electricity generation. The burning of coal leads to emission of gases such as oxides of carbon, oxides of sulphur, oxides of nitrogen and water vapour. All these go straight into the atmosphere.
Petroleum is primarily used as transportation fuels. The burning of petroleum oils mostly leads to the emission of oxides of carbon and sulphur together with water vapour into the atmosphere.
Iron(III) sulfide is the name of the compound written using the Stock system. In the Stock system (named for Alfred Stock) a Roman numeral is used to indicate the oxidation number of the metal. Roman numerals are used in the names of compounds where the metal exhibits two or more oxidation states.
The sum of the oxidation states of a compound must always be zero. The oxidation state of sulfide is -2, and the oxidation state of sulfur, we are told by (III) is +3. You can either use the "criss-cross" trick to get the subscripts where the oxidation number of Fe becomes the subscript of S, and the oxidation number of S becomes the subscript of Fe...
+3-2
.FeS --> Fe2S3 .
