A student made the table below to compare high air pressure and low air pressure. Which correction is required to make the table correct Answers: high pressure results in clear skies, high pressure results in less air below pressing up, low pressure results in more air above pressing down, or low pressure results in sunny weather.

An ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 95 kpa and 27°c, and 750 kj/kg of heat is transferred to air during the constant-volume heat-addition process. assuming constant specific heats at room temperature, determine (a) the pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. (4390 kpa, 1730 k; 423 kj/kg; 56.4%; 534 kpa)
