A chemistry graduate student is designing a pressure vessel for an experiment. The vessel will contain gases at pressures up to 220.0 MPa.
The student's design calls for an observation port on the side of the vessel (see diagram below). The bolts that hold the cover of this port onto
the vessel can safely withstand a force of 10.00 MN.

Cup A contains a larger volume of water than cup B, denoted in the below as the "extra water". A
ball is placed in container B as shown, which floats and causes the height of the water in B to rise
and match that of A. Each cup sits on an identical scale to measure its total weight of cup +
contents. Which statement is true regarding the scale readings?
They are equal because the ball compresses the water so that it has a higher density in Cup B than in Cup A,
such that the total weights are the same.
Cup A is found to be heavier because the ball is less dense than water.
They are equal because the weight of the ball is equal to the weight of the extra water.
Cup B is found to be heavier because it contains the balI.
Cup A is found to be heavier because it contains the extra water.
