One of the calculations you will perform using the LabQuest is taking into account the increase in air pressure inside the flask as the temperature increases. The relevant formula is given in the lab manual as: P room I room Pair where Proom and Troom is the pressure and temperature of the lab room respectively. You will be required to rearrange this equation into the form Pair = AT, where A is a constant. If Proom = 104.6 kPa and...

You are asked to perform preliminary calculations to model the effect of the compressor compression ratio on the performance of an aircraft powered by an ideal turbojet engine. The velocity of the aircraft is 280 m/s. The temperature and pressure of air entering the engine are 230 K and 40 kPa, respectively. The maximum temperature achieved in the combustion chamber is 1600 K a) Derive the set of equations necessary to calculate the propulsive efficiency of the aircraft as a...

can you answer both questions please. TIA
In this lab, you will start off by calculating the number of moles of air molecules inside a flask containing 10 mL of water by cooling the flask down to near 0°C and assuming the vapour pressure of water is negligible at that temperature If the volume of the air inside the flask is 148.2 ml, the gas pressure sensors reads 99.6 kPa and the temperature sensor reads 2.7 °C, how many moles...

2) Deriving Expressions for Entropy Generation In this problem you will use your combined 1 and 2"d Law knowledge to derive two expressions, given in lecture without proof, for the rate of entropy generation in different systems. a) A resistance heater is operating steadily in a room filled with ideal gas. The room can be approximated as air-tight, but it exchanges heat with the surroundings to maintain a inside the room, where I and Vare constant temperature Troom. Show hurinside...

can you please solve all three questions. TIA
The boiling point of water at 1 atm is 100°C and the boiling point of ethanol at the same pressure is 78°C. Which one has the higher vapour pressure at a particular temperature? Select one: O They will have the same vapour pressure Ethanol O Water Check In this lab, you will determine the vapour pressure of water or ethanol (P) at various temperatures and use this data to find the enthalpy...

Please tell me if these workings are correct? If not, could
you please help me correct my mistakes. Im not sure if I need to

please.
Why do we measure the volume of the flask in this experiment with water rather than using the volume listed on the side? Select all correct answers that apply. Must include all correct answers for full credit. The volume is not accurate on a flask to the number of significant figures required for this experiment The volumetric markings on the flask do not extend to it's full height...
