25 points The temperature of the earth's atmosphere varies according to the equation T=-0.0052 + 288.15 where T is in Kelvin and z is in meters. If the air temperature at ground level is is °C and pressure is 760 mm Hg. Assume air to be an ideal gas with an average molecular weight of 28.9 g/mol. At an elevation of 5,575 m what is the corresponding pressure in mm Hg? 0 380 0 280 480 O 880

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature

What is creep? what is stress relaxation?
