- Q23(i) Write any two applications of Kinetic Theory of gases.my topic is "Hazard placards on compressed gases For this assignment, you will be working in a small group to research the scenario indicated in the title of your group and explain how it is dependent on the properties of gases that you learned about in this module. You will compile your research in a short wiki page. The expectations for your group are as follows: • Each group member will research and contribute one source related to the application of gaseous properties to your assigned topic.1. The compressibility factor Z = PV/nRT for O2 at -27.1°C and 537.1 atm is 1.50; at 147.4°C and 95.5 atm, it is 1.02. A certain mass of oxygen occupied a volume of 3.28 L at 147.4°C and 95.5 atm. Calculate the volume occupied by the same quantity of oxygen at -27.1°C and 537.1 atm. 2. The composition of a mixture of gases in percentage by volume is 20.5% nitrogen, 15.7% carbon monoxide, 37.8% water, and the rest sulfur dioxide. Calculate the density of the gaseous mixture at 39.8°C and 1.46 atm in grams/liter. Report your answer to the hundredths position.

- High-pressure liquid chromatography (HPLC) is a method used in chemistry and biochemistry to purify chemical substances. The pressures used in this procedure range from around 500 kilopascals (500,000 Pa) to about 60,000 kPa (60,000,000 Pa). It is often convenient to know the pressure in torr. If an HPLC procedure is running at a pressure of 1.45x107 Pa, what is its running pressure in torr? Express the pressure numerically in torr. ► View Available Hint(s) 1.45x107 Pa = VE ΑΣΦ ? torrIdeal Gas Law The pressure P, temperature T, and volume V ofan ideal gas are related by PV = nRT, where n is the number ofmoles of the gas and R is the universal gas constant. For the pur-poses of this exercise, let nR = 1; therefore, P = T/V.a. Suppose that the volume is held constant and the temperatureincreases by ∆T = 0.05. What is the approximate change inthe pressure? Does the pressure increase or decrease?b. Suppose that the temperature is held constant and the volumeincreases by ∆V = 0.1. What is the approximate change in thepressure? Does the pressure increase or decrease?c. Suppose that the pressure is held constant and the volume in-creases by ∆V = 0.1. What is the approximate change in thetemperature? Does the temperature increase or decrease?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:…
