STAGE 1

boyles law states that for a given mass of perfect gas

• volume is inversely propertional to temperature
• pressure is directly proportional to the temperature
• volume is inversely propertional to the pressure
• volume is indirectly propertional to pressure

If the temperature of working substance does not change during the process, while its pressure and volume changes it is said to be

• isochoric process
• isothermal process
• adiabatic process
• condensation process

the general gas equation is given as

• pv=MrT
• Pv=mRT
• pv=mRT
• PV=MrT
