Question

a sample of nitrogen gas occupies a volume of 1l at a pressure of 0.2 bar at 60°. calculate the pressure if the gas is compressed to 0.225l at -3°c?

Answer 1

Pressure= 1 atmVolume = 2 LTemperature = 25oC = 273+25=298 KPV=nRTn=PVRT=1×20.0821×298=0.0817This gas was compressed to a Volume =0.5mL=0.5×10−3LTemperature=−13oC=273+(−13)=260 KP=nRTV=0.0817×0.0821×2600.5×10−3=3.49×103atm
