1. Airplane takeoff from an aircraft carrier is assisted by a steam-driven piston/cylinder with an average pressure of 1250 kPa. A 17 500-kg airplane should accelerate from zero to 30 m/s, with 30% of the energy coming from the steam piston. Find the needed piston displacement volume.

Calculate the work done (J) by 9 mole of O2 (gas) when it expands reversibly at a constant pressure of 3.25 atm. The temperature of the gas is found to increase from 131 K to 505 K. O a. -55969.8 O b. -83954.8 C. -13992.5 O d. -27984.9

Two moles of ideal gas at 4.0 × 105 Pa are contained in an enclosed cylinder with a movable piston.  The cylinder contraption is immersed in ice water so as to keep it at a constant temperature. i) What is the pressure if the volume is doubled?  ii)If, after the volume is doubled, one mole of the gas is vented out of the contraption, then what is the pressure?  Note: choose closes to the given aswers: a) 1.0 × 105 Pa, b) 2.0 × 105 Pa, c) 3.0 × 105 Pa, d) 4.0 × 105 Pa, e) 5.0 × 105 Pa

20 cm3 bulb contains 0.02 moles of ideal gas at a temperature of 270C.Calculate the pressure inside the bulb (Universal gas constant=8.314JK-1mol-1 ).

Amanda discovers that the gauge pressure in her car tires is 2.50 ×105 Pa at a temperature of 35.0oC. The average volume of a single tire at that temperature is 10.0 L. 1.) Find how many moles of gas (air) are in one of Steve’s tires.   2.) Later Amanda travels to a place where the temperature is –40.0oF. She notices that the tires are looking low and estimates that each tire has lost approximately 1.0 L of its volume. What is the gauge pressure in the tire now?

1. Gas in a container is at 1.6 bar and 4.0 m'. What is the work done by the gas if it is compressed to one-fifths of its initial volume?

a) An ideal gas occupies a volume of 1.6 cm3 at 20°C and atmospheric pressure. Determine the number of molecules of gas in the container.    molecules (b) If the pressure of the 1.6 cm3 volume is reduced to 1.2 ✕ 10-11 Pa (an extremely good vacuum) while the temperature remains constant, how many moles of gas remain in the container?  mol       example of question a  An ideal gas occupies a volume of 2.4 cm3 at 20°C and atmospheric pressure.
