NEET Physics Kinetic Theory of Gases Questions Solved

Three containers of the same volume contain three different gases. The masses of the molecules are m1, m2 and m3 and the number of molecules in their respective containers are N1, N2 and N3 . The gas pressure in the containers are P1, P2 and P3 respectively. All the gases are now mixed and put in one of the containers. The pressure P of mixture will be

1. P<P1+P2+P3                               

2. P=P1+P2+P33

3. P=P1+P2+P3                                 

4. P>P1+P2+P3

3. According to the Dalton’s law of partial pressures, the total pressure will be P1+P2+P3.
