During an experiment, an ideal gas is found to obey a condition `Vp^2 =` constant. The gas is initially at a temperature (T), pressure (p) and volume (V). The gas expands to volume (4V).

Options

A. The pressure of gas changes to P/2
B. The temperature of gas changes to 4T
C. The graph of the above process on P-T diagram is parabola
D. The graph of the above process on P-T diagram is hyperbola

Answer

A, D

Explanation

`VP^2 = "constant "rArr VP^2 = 4 V (P^2) rArr P' = P//2 rArr "PT = constant " rArr PT = P/2 T' rArr T' =2T`
