The average translational kinetic energy of N 2 gas molecules at _ _ _ _ _ _ _ _ _ C ∘ becomes equal to the K . E . of an electron accelerated from rest through a potential difference of 0 . 1 volt . (Given k B = 1 . 38 × 10 - 23 J K - 1 (Fill the nearest integer).
Correct answer
0
Step-by-step solution
Given Translation K . E . of N 2 = K . E of electron 3 2 k T = e V 3 2 × 1 . 38 × 10 - 23   T = 1 . 6 × 10 - 19 × 0 . 1    ⇒ T = 773   K T = 773 - 273 = 500 ° C
