NEET 2026 Physics question
A flask contains argon and chlorine in the ratio of 2 : 1 by mass. The temperature of the mixture is C. The ratio of root mean square speed of the molecules of the two gases is: (Atomic mass of argon = 40.0 u and molecular mass of chlorine = 70.0 u)
Answer: (1)
Solution
. Both gases are at the same temperature (the mixture is in thermal equilibrium), so and the mass ratio 2 : 1 is
