1.
The mechanical advantage (eta) of an ideal hydraulic press equals all of the following ratios EXCEPT:
Force on the large piston / Force on the small piston (F / f)
Area of the large piston / Area of the small piston (A / a)
Distance moved by the small piston / Distance moved by the large piston (y1 / y2)
Work done by the large piston / Work done on the small piston > 1
2.
A mercury manometer connected to a gas tank shows the mercury level in the free arm is 4 cm higher than the gas arm (Pa = 76 cm Hg). The gas pressure is:
72 cm Hg
4 cm Hg
76 cm Hg
80 cm Hg
3.
Real gases behave most closely to an ideal gas under conditions of:
High pressure and near liquefaction point
Zero gravitational acceleration
Very low pressure and high temperature (where intermolecular attraction forces and molecular volumes become negligible)
Extremely high pressure and low temperature
4.
