Oxygen (molar mass 32 kg/kmol) expands reversibly in a cylinder behind a piston at a constant pressure of 3 bar. The volume initially is 0.01 m3 and finally is 0.03 m3; the initial temperature is 17°C. Calculate the work input and the heat supplied during the expansion. Assume oxygen to be an ideal gas and take cp = 0.917 kJ/kg K. For 1 bonus mark explain why (using your understanding of thermodynamics) that oxygen is used in this context rather than water vapour.

### To make a conclusion for a report of an experiment on rockets, in which the openrocket software was used for the construction and modeling of two rockets: one one-stage and one two-stage.
First rocket (single-stage) reached a maximum vertical speed of 200 m/s and a maximum height of 1000 m
The second rocket (two-stage) reached a maximum vertical speed of 250 m/s and a maximum height of 1800 m
To make a simplified conclusion, taking into account the efficiency of the software in the study of rockets
