Question

atmospheric pressure is 1.02 atm. Under these conditions the gauge pressure is measured to be 1.7 atm (about 25 lb/in.2) is After the car is driven on the highway for 30 min, the temperature of the air in the tires has risen to 45oCand the volume has risen to 0.0153 m3. What then is the gauge pressure? 191 atm 0/1 points I Previous Answers YF14 18 XP 013 My N A canister of 1.20 mol of nitrogen gas (28.0 g/mol) at 11.4°C is left on Jupiter's satellite after completion of a future space mission. Europa has no appreciable atmosphere, and the acceleration due to gravity at its surface is 1.30 m/s2. After some time, the canister springs a small leak, allowing molecules to escape through a small hole. What is the maximum height (in km) above Europa's surface that a N2 molecule having speed equal to the rms speed will reach if it is shot straight up out of the hole in the canister? Ignore the variation in g with altitude.

Explanation / Answer

Here ,

for the rms speed of the molecules

v = sqrt(3 * R * T/M)

v = sqrt(3 * 8.314 * (11.4 + 273)/.028)

v = 503.3 m/s

for the maximum height

maximum height attained by the atoms = v^2/(2 * g)

maximum height attained by the atoms = 503.3^2/(2 * 9.8)

maximum height attained by the atoms = 12924.0 m = 12.9 km

the maximum height attained by the atoms is 12.9 km
