# can someone show me how to answer this ?

A cylinder contains 0.24 kg of air that is initially at temperature of 282 K. The cylinder is fitted at the top end with a piston that exerts pressure at 152 kPa at this initial state. Air was heated to a final state where the temperature reached 498 K while the cylinder was allowed to move to a new position. At this final state, the pressure increased to 206 kPa . Calculate the volume of air in the cylinder at the final state in cubic meters. Give the answer in three significant figures. You can assume that air obeys the ideal gas law: PV=mRT, Take R for air to be 0.287 kJ/kg K.
