Three processes of an ideal gas are drawn on a P-T graph: (1) a straight line through the origin, (2) a vertical line parallel to the P axis, (3) a horizontal line parallel to the T axis. Which statement is correct?
Options:
Answer:
A
Solution:
On a P-T line through the origin (P)/(T) = constant, so V and the density are constant. On the vertical line T is fixed and P rises, so V falls and the density rises. On the horizontal line P is fixed and T rises, so V rises and the density falls. A.
