There are two containers of equal volumes, each filled with a different gas. both containers have the same number of moles of gas and are at the same temperature. the molecules of gas in container 1 are four times more massive than the molecules of gas in container 2. state which container, 1 or 2, has the larger value of the following quantities, or, if they are equal, state that they are equal. explain your reasoning. ( show any formulas and calculations used.)
i) pressure
ii) "average" (rms) speed of gas molecules
iii) average kinetic energy of gas molecules
iv) thermal energy

Ogle–2013–blg–0723 is an exoplanet that is similar to earth in size and proximity to its star. this exoplanet has mass m=4.18×1024kg and radius r=5.66×106m. an astronaut whose weight on earth is w=735n lands on the planet. a. calculate m, the mass of the astronaut. b. calculate gp? , the acceleration due to gravity on the surface of ogle–2013–blg–0723. c. calculate wp? , the weight of the astronaut on the surface of ogle–2013–blg–0723. d. calculate v, the minimum velocity required to put an object into orbit above ogle–2013–blg–0723. e. calculate t, the time required to complete an orbit around ogle–2013–blg–0723.
