`0.01` moles of an ideal diatomic gas is enclosed in an adiabatic cylinder of cross-sectional area `A=10^(-4)m^(2)` In the arrangement shown, a block of mass `M= 0.8` kg is placed on a horizontal support, and piston of mass `m=1` kg is suspended from a spring of stiffness constant `k=16 N//m` Initially, the springs is relaxed and the volume of the gas is `V= 1.4 xx10^(-4)m^(3)` When the gas in the cylinder is heated up the piston starts moving up and the spring gets compressed so that the block M is just lifted up. Determine the heat supplied (in Joule) Take atmospheric pressure `P_(0)=10^(5) Nm^(-2) , g=10 m//s^(2)` |

Answer» Correct Answer - `0075` J `DeltaV=f/2nRDeltaT=5/2(P_(2)V_(2)-P_(1)V_(1))=63` J `mgx+1/2kx^(2)+P_(0)Ax=omega_(gas)` `Omega_(gas)=12 j Rightarrow DeltaQ=75J` |
