The time limit for. shipping a POV is the same as for travel and HHG transportation limits (JTR Para 5366, POV. Transportation Time Limitation), 1 year from the date of retirement/separation with severance. pay or 180 days from the date of separation.
The envelope is the large bag that holds the helium gas. The envelope is generally cigar-shaped, for aerodynamic purposes, and made of a durable, airtight, lightweight fabric (polyester composites) that is much like the fabric of a space suit.
Q19. A sample of helium occupies 521 ml at 1572 torr. Assume that the temperature is held constant and determine (a) the volume of the helium at 752 torr; (b) the volume of the helium at 3.55 atm; (c) the pressure in torr, if the volume is changed to 315 ml (d) the pressure in atm if the volume is changed to 2.75 ml.Q20.ssume that the temperature is held constant and determine (a) the volume of the helium at 752 torr; (b) the volume of the helium at 3.55 atm; (c) the pressure in torr, if the volume is changed to 315 ml (d) the pressure in atm if the volume is changed to 2.75 ml.
