A diatomic gas is heated at certain pressure. What fraction of the heat energy is used to increase the internal energy?

Options

  1. A3 / 5
  2. B3 / 7
  3. C5 / 7
  4. D5 / 9

Correct answer

C. 5 / 7

Step-by-step solution

f= V ( Q_p ) = Q_V ( Q_p )_p = C V T C p T = 1 T aligned & f= 7 5 & f= 5 7 aligned
