Tooling for a vacuum deposition system is cleaned and reassembled. Unfortunately, a drop of water 0.125 cm3 in volume is left in the bottom of a screw hole. Due to the obstructed path to the pump, a negligible amount of water escapes during the early stages of pumpdown, and the drop becomes a virtual leak at a chamber pressure of 4.3E-06 torr. Find the volume of gas formed by the water at this pressure (assume it stays at room temperature). The density of water is 1g cm-3 and the molecular weight 18 g mole-1. (First, determine the number of moles in the drop of water, and use the ideal gas law to determine the volume) (b) To make this result clearer, what is the added time (in hours) to pump out this chamber due to this droplet if the pump, at that pressure, has a rate of 1480 L/s?

Using the equation for the best linear fit to the data (1128.8x + 0.5934), determine the pressure (in atm) in the syringe, if the gas volume was 9.20 mL. (HINT. 1 atm = 760 torr, 1 atm = 760 mm Hg, 1 atm = 101.325 kPa)

A natural gas well contains methane, which is practically an ideal gas. The pressure at the surface is 1000 psi. a) What is the pressure at a depth of 20,000 ft if temperature is assumed constant at 70°F? b) How much error would be made by assuming that methane was a constant-density fluid at 70°F? c) If temperature decreases at an approximate constant value of 0.070°R per ft of elevation, what is the temperature and pressure at a depth of 20,000 ft?

Gas bulb A has a volume of 6.00 dm3 and contains N2 gas at a pressure of 200 kPa. Gas bulb B has a volume of 4.00 dm3 and contains O2 gas at a pressure of 150 kPa. The two bulbs are connected through a stopcock with negligible volume. When the stopcock is opened, the two gases mix. What is the pressure of the resulting gas mixture?

Thank you

8g of potassium trioxochlorate(v) KCLO3 was heated to liberate oxygen.The gas was collected over water at 301K and a pressure of 90KPa What is the volume of the dry oxygen gas at Stp. (Mr:KCLO3=122.5,O2=32.0,molar volume of gas at S.T.P=22.4dm3 Satured vapour pressure of water at 301K=37kPa.)

The term “airbag” itself is misleading since there’s no significant “air” in these cushions. They are, instead, shaped and vented nylon-fabric pillows that fill, when deployed, with nitrogen gas. They are designed to supplement seatbelt restraints and help distribute the load exerted on a human body during an accident to minimize the deceleration rate and likelihood of injury. But while “supplement the seatbelt” is the mission of airbags, federal regulations require that they be tested and made effective for unbelted occupants, vastly complicating their task. Airbags must do their work quickly because the window of opportunity—the time between a car’s collision with an object and an occupant’s impact on the steering wheel or instrument panel—lasts only milliseconds. For illustration’s sake, imagine a Corvette hitting a bridge abutment head-on at 30 mph. The clock starts the instant the tip of the car’s nose hits the concrete. The Mechanics There are six main parts of an airbag system:…
