. 1 mole of ideal monoatomic gas at 27°C expands adiabatically against a constant external pressure of 1.5 atm from a volume of 4dm3 to 16 dm3.
Calculate (i) q (ii) w and (iii) ΔU
Dear KUNDAN
workdone = 1.5( 16-4)
=18
since in adiabatic process no heat transfer take place so dq =0
and dq =dU +dW
dU=-dW =-18
