1. In a hydraulic system where the area of piston A1 is 3 in.²& the area of A2 is 11.3 in.², how much weight can be lifted at A2 if a force of 23 pounds is applied at A1?

2. A 1.5 Liter stainless steel vessel containing nitrogen gas @ a gauge pressure of71 lbs. per in² & 119 ^oC is placed in a freezer and cooled to 25 ^oC. What would its pressure at the reduced temperature?

3. If 383 cubic inches of O² gas at 59 psig is compressed to 145 cubic inches w/o changing its temperature, what will be the final pressure of the O² gas expressed as a gauge pressure?

4. If both the volume and the absolute temperature of a confined gas are increased by a factor of 4, the absolute pressure will increase by a factor of what?

5. A108cubic inchvolume of chlorine gas is heated from45 C to88 C at constant pressure. What is the final volume?

6. A 500 in.³ SCUBA tank with an initial gauge pressure of 177 lbs. per in² is heated from 71 ^oF to 115 ^oF. What would be its pressure at this increased temperature?

7. If the volume of a confined gas is increased by a factor of 17 (without the addition of more gas), the pressure will change by a factor of what?(assume the temperature remains constant)
