The state of an ideal gas was changed three times in a way that the pressure stays the same. The graph represents three isobaric lines. Which of the following is true about the pressure of the gas? (A) P1 > P2 > P3 (B) P1 > P2 < P3 (C) P1 < P2 < P3 (D) P1 = P2 > P3 (E) P1 > P2 = P3 The temperature of an ideal gas increases from 20 to 40 while the pressure stays the same. What happens to the volume of the gas? (A) It doubles (B) It quadruples (C) It is cut to one-half (D) It is cut to one-fourth (E) it slightly increases The state of an ideal gas was changed three times in a way that the volume stays the same. The graph represents three isobaric lines. Which of the following is true about the volume of the gas? (A) V1 >V2 >V3 (B) V1 > V2 < V3 (C) V1 < V2 < V3 (D) V1 = V2 > V3 (E) V1 > V2 = V3
