Problem

During an experiment, an ideal gas is found to obey a condition

Vp^2 = \text{constant}

. The gas is initially at a temperature

T

, pressure

p

and volume

V

. The gas expands to volume

4V

. (1) The pressure of gas changes to

\frac{p}{2}

(2) The temperature of gas changes to

4T

(3) The graph of the above process on

p-T

diagram is parabola (4) The graph of the above process on

p-T

diagram is hyperbola
