A monoatomic ideal gas is heated at constant pressure. The percentage of total heat used in changing the internal energy is

Options

  1. A30 %
  2. B40 %
  3. C50 %
  4. D60 %

Correct answer

D. 60 %

Step-by-step solution

For a monoatomic gas, = C_ P C _ V = 5 3 We know Q = nC _ p T and U = nC _ v T U= nC _ V ~T Q = nC _ p ~T = C _ V C _ P = 3 5 The percentage of total heat used in changing the internal energy is 3 5 100=60 % .
