Answer published by the source. Consult the official source to check your work against its answer.

question

The escape velocity, the speed at which molecules can escape the earth's gravitational field, is approximately 1.1 × 10^6 cm sec^-1 (about 7 miles sec^-1). At what temperature, approximately, will the root mean square velocity value for H_2 be equal to the escape velocity? (R = 8.3 × 10^7 erg mole^-1 deg^-1 ; at. wt: H = 1)
