### Question Asked by a Student from EXXAMM.com Team

Q 1177080886.     An ideal gas in thermally insulated vessel at internal pressure = p_1, volume = V_1 and absolute temperature = T_1 expands irreversibly against zero external pressure, as shown in the diagram.
The final internal pressure, volume and absolute temperature of the gas are p_2, V_2 and T_2, respectively. Which of the following is true for this expansion?

(This question may have multiple correct answers)

A q = 0
B p_2V_2 = p_1V_1
C p_2V_2^γ=p_1V_1^γ
D T_2 = T_1
