1.
In a hydraulic press, the ratio of the cross-sectional area of the large piston to that of the small piston is 50. If a force of 100 N is exerted on the small piston, the maximum force exerted by the large piston is:
2 N
5000 N
50,000 N
2500 N
2.
In a hydraulic press, if the radius of the large piston is 4 times that of the small piston, the mechanical advantage is:
4
2
16
8
3.
Boyle's Law states that for a fixed mass of an ideal gas kept at constant temperature, the volume V is:
Directly proportional to pressure
Directly proportional to absolute temperature
Independent of pressure changes
Inversely proportional to its absolute pressure P (P1 * V1 = P2 * V2)
4.
A fixed quantity of an ideal gas has a volume of 600 cm3 at 27 °C. If the gas is heated to 127 °C under constant pressure, its new volume will be:
800 cm3
700 cm3
900 cm3
1200 cm3
5.
If both the absolute temperature and the absolute pressure of a confined ideal gas are doubled, the volume of the gas:
Decreases to one-fourth
Quadruples
Remains constant and unchanged
Doubles to twice its original volume
6.
The volume expansion coefficient at constant pressure (alpha_v) of an ideal gas is physically measured using:
A venturi meter and manometer
A hydrometer
A torsion balance
Joly's bulb apparatus or Charles's apparatus with a dry mercury droplet index
