Given below are two statements: Statement-I: For isothermal irreversible change of an ideal gas, q=-w= P _ ext ( V _ final - V _ initial ) Statement - II: For adiabatic change, U = W _ adiabatic The correct answer is

Options

  1. ABoth Statement-I and statement-II are correct
  2. BBoth Statement-I and statement-II are not correct
  3. CStatement-I is correct but statement-II is not correct
  4. DStatement-I is not correct but statement-II is correct

Correct answer

A. Both Statement-I and statement-II are correct

Step-by-step solution

For isothermal process, U =0 q =- w = (- P _ ext V )= P _ ext ( V _ final - V _ initial ) for adiabatic process, q=0 U=w_ adibatic
