Question #954aa

Answer 1

It is at constant temperature, a consequence of Boyle's law.

Explanation:

The ideal gas equation states `pV = nRT` where p is pressure, V is volume, n is amount of substance (no. of moles), R is gas constant and T is temperature.

If temperature remains constant, then because the amount of substance is constant, and the gas constant is, of course, constant, then it means that `nRT` is constant (`pV =` constant is Boyle's law).

So if `pV =` a constant, it means that a plot of pV against p is a straight line which is parallel to the x axis.
