Question

bulb.
(iii) Find the odd one out :
C2H4, C4H10, C3H2, CH4
(iv) Complete the correlation :
Resistance : The ohm :: Potential difference :
(v) State the relation between the refractive index and th
critical angle.
(A) Give scientific reasons : (Any two)
(i) In winter, the pipelines carrying water burst in colo
countries.
(ii) Geostationary satellites are not useful for studies of pola
regions.
(iii) Zero group elements (inert gases) are called noble gases.​

Answer 1

Answer:

iii)C³H²

iv)Capacitor

v)critical angle is inversely proportional to refractive index

A

i) pipeline in the winter burst because when the temperature falls down to the 4° Celsius then the water will expands and that's why the temperature may reach to the 0° Celsius

ii)

iii) In the atoms of the inert gas elements (zero group elements), all the electronic shells, including the outermost shell, are completely filled.
