JEE Main 27 June 2022, Shift 2, Physics Q37

Question 37 of 90 in this shift, Physics question 7 of 30, Section A.

For a perfect gas, two pressures P1_1 and P2_2 are shown in figure. The graph shows :

The figure, in words

Graph with vertical axis labelled Volume (V) and horizontal axis labelled Temperature (T), origin marked O. Two straight rising lines, both starting a little above the T axis and away from the vertical axis: the steeper line is labelled P2 and the less steep line is labelled P1.
  1. (1)P1>P2P_1 > P_2Official answer
  2. (2)P1<P2P_1 < P_2
  3. (3)P1=P2P_1 = P_2
  4. (4)Insufficient data to draw any conclusion
