JEE Main2012PhysicsThermodynamicsActual
A given ideal gas with = C_p C_v =1.5 at a temperature T . If the gas is compressed adiabatically to one-fourth of its initial volume, the final temperature will be
Options
- A2 2 T
- B4 T
- C2 T
- D8 T
Correct answer
C. 2 T
Step-by-step solution
T V^ -1 = constant aligned & T₁ V₁^ -1 = T ₂ V₂^ -1 & T(V)^ 1 / 2 = T ₂ ( V 4 )^ 1 / 2 & [ =1.5, T₁=T, V₁=V and V₂= V 4 ] & T₂= ( 4 V V )^ 1 / 2 T=2 T aligned
