Which one of the following is applicable for an adiabatic expansion of an ideal gas?

Which one of the following is applicable for an adiabatic expansion of an ideal gas?
  1. $\Delta E=0$
  2. $\Delta W = \Delta E$
  3. $\Delta W = - \Delta E$
  4. $\Delta W = 0$

Solution

$\Delta E=q+W$ For an adiabatic reaction, $\Delta q=0$ So, $\Delta E=\Delta W$ /
