An equimolar mixture of a monoatomic and a diatomic ideal gas is suddenly compressed to 1 8 th of its original volume. The ratio of final temperature to the initial temperature.

Options

  1. A8^ 0.53
  2. B8^ 0.5
  3. C8^ 1.53
  4. D8^ 2 / 3

Correct answer

B. 8^ 0.5

Step-by-step solution

For the mixture, = C_P^ (1) +C_P^ (2) C_V^ (1) +C_V^ (2) = 7 2 R+ 5 2 R 5 2 R+ 3 2 R = 3 2 Applying TV ^ -1 = constant, the temperature increases by a factor of 8 .
