An insulated container containing monoatomic gas of molar mass s is moving with a velocity `v_0`. If the container is suddenly stopped, find the change in temperature. |
|
Answer» Correct Answer - B::C When container is stopped, velocity decrease by `v_0.` `Therefore change in kinetic energy=1/2(nm)v_0^2…..(i)` Here n=number of moles of gas present in the container. The kinetic energy at a given temperature for a monatomic gas is `=3/2xxnRT` `:. Change in kinetic energy =3/2xxnR(DeltaT).....(ii)` where `DeltaT=Change in temperature` From (i) and (ii) `3/2nR(DeltaT)=1/2(nm)v_0^2 :. DeltaT=(mv_0^2)/(3R)` |
