14. ***A gas inside a cylinder expands from 4.2 L to 8.7 L at a constant pressure of 5.1 x 10^3 Pa. What work is involved in this process? REMEMBER! You must convert L to m^3!!! 1 L = 0.001 m^3. Please help me with this question ;O;

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)
