Q7

During one compression stroke ( process) in an engine , 0.30 moles of air ( a diatomic ideal gas ) are compressed adiabatically from an initial volume and temperature of V1= 5.3 L and T1=277K to final volume of V2=0.9 L . What is the magnitude ( absolute value) of the work done by the gas during this process?

( Note : this is also the work done by the piston on the gas to compress the gas. the work done by the gas is negative ,the work done on the gas is positive.)

give your answer in Joules to at least3 digits to avoid being counted incorrect due to rounding. Do not include the units in your answer .

Be sure to remember that this is a diatomic gas .
