1.	Heat absorbed by the gas undergo a cylic process along closed path in one complete cycle as shown in figure will be _____J.
Answer» `10^7pi` `10^4 pi` `10^2 pi` `10^(-3)pi` Solution :For CYCLIC PROCESS `DeltaU=0` Heat change for a system `DELTAQ=DeltaU+DeltaW` `DeltaQ=DeltaU+Delta(PV)` `therefore DeltaQ` = Area under the graph, `=pir^2kPaxx"lit"` `=pi((30-10)/2)^2` kPa x lit `=pi(20/2)^@ kP_a xx "lit"` `=pixx100xx10^3xx10^(-3)` J `=100piJ=10^2 piJ`
