During an isothermal expansion, a confined ideal gas does $-150 \,J$ of work against its surroundings. This implies that
  • A$150 J$ of heat has been removed from the gas
  • B$300 J$ of heat has been added to the gas
  • C
    no heat is transferred because the process is isothermal
  • D$150 J$ of heat has been added to the gas
