1.	Containers A and B have same gas. Pressure, volume and temperature of A are all twice that of B. Then the ratio of the number of molecules of A and B are
Answer» <P>`1:2` `2:1` `1:4` `4:1` Solution :For B,`P_(1)=P,V_(1)=V,T_(1)=T`. For A, `P_(1)=2P,=2P,V_(2)=2P,T_(2)=2T` Applying ideal gas EQUATION, Pv=nRT. `(P_(1)V_(1))/(n_(1)RT_(1))=(P_(2)V_(2))/(n_(2)RT_(2))" or " (PV)/(n_(1)RT)=(2pxx2V)/(n_(2)R(2T))` or `(n_(2))/(n_(1))=(2)/(1)`
