A) Pressure Temperature increase increase
B) decrease decrease
C) increase decrease
D) decrease increase
Correct Answer: B
Solution :
According to first law of thermodynamics \[\Delta Q=\Delta U+\Delta W\] For an adiabatic process \[\Delta Q=0\] \[\therefore \] \[\Delta U=-W\] In adiabatic process \[p\propto \frac{1}{{{V}^{\gamma }}}\] and \[T\propto \frac{1}{{{V}^{\gamma -1}}}\] \[\gamma >1\], because volume increases. Then, p and T will decrease.You need to login to perform this action.
