Atechnician is studying the power stroke of a four-stroke engine and determines the following: as the piston is forced down, the mixture of combustion products and air undergoes an adiabatic expansion. the engine is running at 3,200 cycles/min. the gauge pressure immediately before the expansion is 27.0 atm. the volumes of the mixture immediately before and after the expansion are 50.0 cm3 and 400 cm3, respectively (figure below). the time interval for the expansion is one-fourth the period of the cycle. the mixture behaves like an ideal diatomic gas with a specific heat ratio of 1.40. determine the average power (in kw) generated during the power stroke.

Use the library or internet to research each planet. make a chart comparing the following: approximate surface temperature relative surface gravity compared to earth atmospheric gases water in any form: solid, gas, or liquid when you have completed your chart, use the information you have collected to answer the following questions: which is the hottest planet? which is the coldest planet? which planet's temperature is closest to that of earth? (note: water boils at 100°c/212°f. water freezes at 0°c/32°f) which planet has the greatest gravitational attraction? which planet has the least gravitational attraction? which planet's gravitational pull is closest to that of earth? do any of the planets have oxygen in their atmosphere? which planet's atmosphere most resembles that of earth? do any of the planets have flowing water? which planet's water resources (solid, gas, or liquid) might be close to the amount on earth? which planet most resembles earth in terms of all of the factors: temperature, gravity, atmosphere, and water? if earth became an uninhabitable planet, which planet do you think would be the next best to live on? explain your answer.
