1.	A cylinder contains a mixture of helium and argon gas in equilibrium at `150^(@)C`. What is the average kinetic energy for each type of gas molecules?A. `3.26 xx 10^(-21) J`B. `8.76 xx 10^(-21) J`C. `6.28 xx 10^(-21) J`D. `4.14 xx 10^(-21) J`
Answer» Correct Answer - B Both kinds of molecules have the same average kinetic as the temperature is same for both the gas molecules The average kinetic energy of a molecules , `bar(K) = 3/2 k_(B) T` `bar(K) = 3/2 (1.38 xx 10^(-23)J//K) (423K) = 8.76xx10^(-21)J`
