- A sample of a monatomic ideal gas initially at temperature T, undergoes a process during which the pressure of the gas triples and its volume also triples. What is the change in the temperature (AT) of the gas, in Kelvins? A. T B. 8T C.9T D. 7/9 E. T18 OB O O O DA OEFor a planet to have an atmosphere, gravity must be sufficient to keep the gas from escaping The escape speed a particle needs to escape the earth's gravitational attraction is 1.1 x 10 m/s. The motion of projectiles never depends on mass, so this escape speed applies equally to rockets and to molecules in the earth's upper atmosphere. Part A At what temperature does the rms speed of nitrogen molecules equal the escape speed? Express your answer in kelvins.
