% Is what is the volume of helium - a balloon filled with loss?
The same volume of two identical balloons, one with air One is filled with helium. The next day, the volume of air Filled balloons fell 4.2%. % Is what is the volume of helium - A balloon filled with loss? (Ie, air, nitrogen, and a four-minute 5 home Oxygen, and temperature did not change.)
Could be leaking balloon In addition, the same gas pressure inside the balloon to maintain the "disclosure, While "waiting time in a given period a certain amount of loss Gas and inversely proportional to the gas, leaving the balloon is proportional to the square root of Is proportional to the ratio of the average molar mass, such as: (ΔV1) sqrt (M1 2) = (ΔV2) sqrt (㎡) the average mass of the air mass of gas, a weighted average of the 2nd Be a configuration: M1 for = (28 g / is a mall) (4 / 5) + (32 g / is a mall) (1 / 5) = 28.8 g / is the drive (4.2) sqrt (28.8 g / is) = (ΔV2) sqrt (4 g /'s Mall) Mall ΔV2 = 11.3% reduction
