1.	At 27^(@)C, average translational kinetic energies of the molecules in 8g of CH_(4),8g of O_(2) and 8g of He are overline(in_(1)),overline(in_(2)) and overline(in_(3)) respectively and total kinetic energies of the molecules in these gases are E_(1),E_(2) and E_(3) respectively. which of the following is true-
Answer» `overline(in_(1))=overline(in_(2))=overline(in_(3))` `overline(in_(3)) gt overline(in_(2)) gt overline(in_(1))` `E_(1)=E_(2)=E_(3)` `E_(2) LT E_(1) lt E_(3)` ANSWER :A
