Q 11-12-012NEETJEE MainEAMCET 2007 (Engineering)Easy
Two gases A and B having the same pressure $P$, volume $V$ and absolute temperature $T$ are mixed. If the mixture has the volume $V$ and temperature $T$ respectively, then the pressure of the mixture is
Answer: (A) $2P$
Each gas alone would exert $P$ in volume $V$ at $T$. By Dalton's law the pressures add: $2P$.
