Answer:
n=6 to n=3 (B)
Explanation:
Energy of an electron present in the
orbit is directly proportional to
.Hence a transistion from one orbit to another orbit emits an energy proportional to the difference of their squares of the orbits. that is if an electron travels from orbit n1 to orbit n2 then it emits an energy corresponding to
.So in the above question the highest energy emission occurs when an electron moves from n=6 to n=3.(Highest difference of energy levels).
Answer:
The rest of the energy is passed on as food to the next level of the food chain. The figure at the left shows energy flow in a simple food chain. Notice that at each level of the food chain, about 90% of the energy is lost in the form of heat.
Answer:
The tabulated values at 120 C of <u><em>hfg = 2202.1</em></u><u> kJ/Kg </u>and <u><em>sfg </em></u><u>= 5.6 </u>
<u>kJ/Kg.K</u>
Explanation:
According to Clapeyron Equation :
![h_{fg}=TV_{fg}\left (\frac{\partial P}{\partial T} \right )_{sat}](https://tex.z-dn.net/?f=h_%7Bfg%7D%3DTV_%7Bfg%7D%5Cleft%20%28%5Cfrac%7B%5Cpartial%20P%7D%7B%5Cpartial%20T%7D%20%20%5Cright%20%29_%7Bsat%7D)
![=T(V_{g}-V_{f})_{120^{0}}\left ( \frac{\Delta P}{\125^{0}-115^{0}} \right )](https://tex.z-dn.net/?f=%3DT%28V_%7Bg%7D-V_%7Bf%7D%29_%7B120%5E%7B0%7D%7D%5Cleft%20%28%20%5Cfrac%7B%5CDelta%20P%7D%7B%5C125%5E%7B0%7D-115%5E%7B0%7D%7D%20%5Cright%20%29)
Taking P2 at temperature 125 and P1 at 115 degree Celsius .
T = 120 + 273.15 = 393.15 K
P2 = 232.23 kPa and P1 = 169.18kPa
(these are experimental values given in the Data)
![= 393.15(0.88133 -0.001060\ m^{3}/Kg)\frac{232.23-169.18 kPa}{10}](https://tex.z-dn.net/?f=%20%3D%20393.15%280.88133%20-0.001060%5C%20m%5E%7B3%7D%2FKg%29%5Cfrac%7B232.23-169.18%20kPa%7D%7B10%7D)
![h_{fg} = 2206.8 kJ/Kg](https://tex.z-dn.net/?f=h_%7Bfg%7D%20%3D%202206.8%20kJ%2FKg)
![S_{fg}=\frac{h_{fg}}{T}](https://tex.z-dn.net/?f=S_%7Bfg%7D%3D%5Cfrac%7Bh_%7Bfg%7D%7D%7BT%7D)
![\frac{2206.8}{393.15}](https://tex.z-dn.net/?f=%5Cfrac%7B2206.8%7D%7B393.15%7D)
= 5.6131 kJ/Kg.K
The tabulated values at 120 C of <em>hfg = 2202.1</em> kJ/Kg and <em>sfg </em>= 5.6131
kJ/Kg.K
im pretty sure, a shade of purple
