a spherical vessel with a diameter of 2cm when empty,
has a mass of 2.00g. what is the greatest volume of water that can
be placed in the vessel and still have the vessel float at the
surface of water?
A spherical vessel (diameter = 5.00 cm) when empty has a mass of
12.00 g. What is the greatest volume of water in mL that can be
placed in the vessel and still have the vessel float at the surface
of benzene? (Given: density of water = 1.00 g/cm3;
density of benzene = 0.879 g/cm3)
A certain spherical eukaryotic cell has a diameter of 51um. If a
spherical organelle has a diameter of 860nm, how many of these
organelles can the cell hold.
Pure gaseous hydrogen at 10 atm is stored in a 10-cm-diameter,
spherical steel pressure vessel having a wall thickness of 3 mm.
The solubility of H2 in steel under these conditions is 0.085 m3
(STP)/(m3 of solid . atm) and the diffusivity of H2 in steel at
300oC is 3.8x10-10 m2 /s (independent of pressure). You may assume
that the H2 partial pressure outside the vessel is zero.
a) Calculate the steady–state rate of leakage (in kmol/h) of H2
from...

____ g
(b) alcohol (density 0.7893 g/cm3 at 20°C)
____ g
(c) mercury (density 13.546 g/cm3 at 20°C)
____ g
(d) Explain why mercury containing pollutants are usually found in
the mud at the bottom of a lake of stream.
-Mercury has a negative charge and is attracted to the
positively charged...
An empty glass container has a mass of 418.634 grams. It has a
mass of 419.514 grams after it has been filled with nitrogen gas at
a pressure of 790 mmHg and a temperature of 15oC. When
the container is evacuated and refilled with a certain element X at
a pressure of 745 mmHg and a temperature of 26oC, it has
a mass of 420.652 grams.
Compound Y, a gaseous organic compound that consists of 88.9%
carbon and 11.1...
When a can of beer is both full and empty, the center of mass is
in the center of the can. As you drink your beer, however, the
center of mass lowers to some minimum point, before returning back
to the center. What is that minimum point?
A vertical vessel with an internal diameter of 84” has a
hemispherical head at the top and an ellipsoidal head of 2:1 at the
bottom. The construction material has a maximum allowable stress of
8700 psi at its design temperature. The operating pressure is
stated as 48 psig. The overall height of the vessel is 38‟ and a
joint efficiency of 1.0 is used.
) Determine the wall thickness of each part of the vessel.
b) If a corrosion allowance...
A rigid, insulated, empty vessel is to be filled with steam from
a steam line at 7 bar and 320°C. Steam flows into the vessel until
the pressure in the vessel is 7 bar. At this instant the valve on
the charging line is closed.
(a) What is the temperature of the
steam in the vessel at the instant the valve is closed?
(b) What is the final pressure of
the steam in the vessel after it has reached mutual stable
equilibrium...
