Multiple Choice
An oxygen (O2) molecule has twice the mass of a methane (CH4) molecule. In a planet's atmosphere at some particular temperature, the average kinetic energy of an oxygen molecule is:
A) the same as that of a methane molecule (that is, all molecules have the same average kinetic energy at the same temperature) .
B) 1.4 times greater than that of a methane molecule (that is, the average kinetic energy increases in proportion to the square root of the mass) .
C) 4 times greater than that of a methane molecule (that is, the average kinetic energy increases in proportion to the square of the mass) .
D) twice that of a methane molecule (that is, the average kinetic energy increases in the same proportion as the mass) .
