The heat energy supplied to a diatomic gas at constant pressure is 210 ~J , then the work done by the gas is

Options

  1. A60 ~J
  2. B150 ~J
  3. C90 ~J
  4. D210 ~J

Correct answer

A. 60 ~J

Step-by-step solution

Heat Q=210 ~J For diatomic aligned & C_V= 5 2 R & C_P=R+C_v & =R+ 5 2 R= 7 2 R aligned Heat, Q = C _ p T =210 7 2 R T =210R T=60 Work done by the gas, W = P V = R T =60 ~J
