The combustion of a fuel usually results in an increase in pressure when the volume isheld constant, or an increase in volume when the pressure is held constant, because ofthe increase in the number of moles and the temperature. The increase in the pressureor the volume is maximized when the combustion is complete and it occursadiabatically with the theoretical amount of air. Consider the combustion of methylalcohol vapor (CH3OH (g)) with stoichiometric amount of air in a 0.8 L combustionchamber. Initially, the mixture is at 25 ºC and 98 kPa. finda)max pressure that can occur if comb. is constant volumeb) max volume if comb is constant pressure

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?
