Heat and Thermodynamics question

2011 · Q157

NEETPhysicsHeat and ThermodynamicsMCQ+4 / −1
During an isothermal expansion, a confined ideal gas does −-− 150 J of work against its surroundings. This implies that
  1. A
    150 J of heat has been removed from the gas
  2. B
    300 J of heat has been added to the gas
  3. C
    no heat is transferred because the process is isothermal
  4. D
    150 J of heat has been added to the gas
