Find the value of Cv and Cp for nitrogen. (Given R = 8.3 J mol-1 K-1 ; also, for a diatomic gas, Cv = \(\frac{5}{2}\) R. |
|
Answer» Nitrogen is known to exist as a diatomic molecule. Hence Cv(for nitrogen) = \(\frac{5R}{2}\) = \(\frac{5}{2}\) × 8.3 J mol-1 K-1 = 20.75 J mol-1 K-1 From Mayer’s relation, Cp = Cv + R Cp(for nitrogen) = (20.75 + 8.3) J mol-1 K-1 = 29.05 K mol-1 K -1 |

|
| 38. |
A concave mirror produces three times magnified (enlarged) real image of an object placed at 10 cm in front of it. Where is the image located? |
|
Answer» M = \(\frac{Height\, of\, image}{Height\, of\, object}\) = \(\frac{h_1}{h_0}\) = \(\frac{-u}{v}\) Let the height of object be h then height of image h = – 3h = \(\frac{3h}{h}\) = \(\frac{-v}{u}\) = \(\frac{v}{u}\) = 3 ∴ Distance of object, u = – 10 cm v = 3 × (10) = – 30 cm Here – sign indicates, image is real and it is 30 cm in front of concave mirror. |
