Question

1) Which of the following statements about pV diagrams is FALSE?

Any isobaric process appears on a pV diagram as a horizontal line.

Every point on a pV diagram has a unique temperature.

Any isochoric process appears in a pV diagram as a vertical line.

Any isothermal process appears on a pV diagram as a parabola.

2) Which of the following statements about hydrostatic equilibrium is FALSE?

The pressure is the same at all points at the same height in a liquid in hydrostatic equilibrium.

In an arbitrary shaped container with connected open pieces, a liquid in hydrostatic equilibrium will rise to the same height at all open regions of the container.

In an incompressible fluid in hydrostatic equilibrium, the pressure must be the same at every point in the fluid.

The pressure of a liquid in hydrostatic equilibrium is due to the balance between the weight of all the fluid above that point balancing the force pushing upward from the fluid below.

Explanation / Answer

Any isothermal process appears on a pV diagram as a parabola.

2)

In an arbitrary shaped container with connected open pieces, a liquid in hydrostatic equilibrium will rise to the same height at all open regions of the container.
