Question

Which law is based on the graph that is shown below?

A graph is shown with pressure on the horizontal axis and volume on the vertical axis. A curve starts high on the horizontal axis, curves toward the origin, and then starts to level out as it approaches the horizontal axis.
Boyle’s law
Charles’s law
Dalton’s law
Gay-Lussac’s law

Answer 1

Boyle’s law.

At constant temperature, pressure and volume are inversely proportional (PV = constant), so a plot of volume versus pressure is a hyperbola: as pressure increases, volume decreases and approaches zero asymptotically.
