There are equal volumes of N_2 and CO_2 gases at 25^@C and 1 atm. Then

1.	There are equal volumes of N_2 and CO_2 gases at 25^@C and 1 atm. Then indicate the correct statements among the following
Answer» The RMS velocity remains the same for `N_2` and `CO_2` gases The average TRANSLATIONAL K.E per molecule is the same for `N_2` and `CO_2` The DENSITY of `N_2` is less than that of `CO_2` The TOTAL translational K.E of both `N_2` and `CO_2` is the same Solution :Equal volumes, P, T = same n average `KE = 3/2 KT , d alpha M` Total KE = `3/2 NRT`.
