Q7 / 160 · AP EAMCET 2022 (04 Jul Shift 2) · Chemistry

From the following plots, find the correct option.

A
$T_{1} > T_{2}; P_{1} > P_{2}$
B
$T_{1} > T_{2} : P_{2} > P_{1}$
C
$T_{2} > T_{1}; P_{2} > P_{1}$
Correct answer
D
$T_{2} > T_{1} : P_{1} > P_{2}$

Solution

For a graph between $P$ and $V$ , If we draw a line parallel to the V axis (P= constant) Then it will intersect two graphs at two position. According to Charles's law as V increases T also increases.
Therefore, $T_{2} > T_{1}$ .
For a graph between $V$ and $T$ , the slope, $(\frac{nR}{P})$ , is inversely proportional to the pressure.
Therefore, $P_{1} > P_{2}$ .

Hence, the correct answer is option: 'D'.
