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» <P> `mgx+1/2kx^(2)+P_(0)Ax=omega_(gas)` `Omega_(gas)=12 j Rightarrow DeltaQ=75J` |
