A flask contains 1.00 mole of oxygen gas, O2, at 0.00 °C and 1.013 × 105 Pa. What is the rms speed of the molecules? Note: the atomic mass of O is 16 u.​

Rain is pulled by gravity which is a non contact force

At maximum height, kinetic energy is converted in potential energy  formula: at max height, ke = ½ * 0.27kg * (16m/s) ² = 34.56 j  so the remaining pe = (41.70 – 34.56)= 7.14 j = 0.27 kg * 9.8m/s² * h  = (9.8/7.14 * 0.27)so max height h = 5.08 or 5 m 

Answerit is comparative because this experiment is comparing the results of the volume at minimal pressure and then increases it; ; ;
