If, as is typical, each of them breathes about 500 cm3 of air with each breath, approximately what volume of air (in cubic meter
deff fn [24]

Answer:

<em>a) 12614.4 m^3</em>

<em>b) 28.8 m</em>

Explanation:

The complete question is

Four astronauts are in a spherical space station. (a) If, as is typical, each of them breathes about 500 cm^3 of air with each breath, approximately what volume of air (in cubic meters) do these astronauts breathe in a year? (b) What would the diameter (in meters) of the space station have to be to contain all this air?

The average breathing rate is 12 breaths per minute

there are 60 minutes x 24 hours x 365 days in a year = 525600 minutes in a year

if an average human takes 12 breath per minute, then in a year an average human take 12 x 525600 = 6307200 breath

For the four astronauts, the amount of breath = 4 x 6307200 = 25228800 breath in total.

The volume of air per breath = 500 cm^3

1 cm^3 = 10^-6 m^3

500 cm^3 = x m^3

x = 500 x 10^-6 = 5 x 10^-4 m^3

Therefore in a year, the volume of these astronauts breath in a year = 5 x 10^-4 x 25228800 = <em>12614.4 m^3</em>

b) If the space station is spherical, the volume will be given as = \frac{4}{3} \pi r^3

where r is the radius of the space station

This volume of the space station must be able to contain all the volume of breath produced by the astronauts which is = 12614.4 m^3

Equating, we have

12614.4 = \frac{4}{3} \pi r^3

12614.4 = \frac{4}{3}*3.142*r^3

12614.4 = 4.1893r^{3}

r^{3} = 12614.4/4.1893 = 3011.1

r = \sqrt[3]{3011.1} =<em> 14.4 m</em>

<em>diameter of the space station = 14.4 m x 2 =  28.8 m</em>

During which phase does the arrangement of water molecules become more orderly?
erastovalidia [21]
I believe the correct answer from the choices listed above is option D. During the condensing phase that the <span>arrangement of water molecules become more orderly. Condensation is the phase change from gas to liquid. Liquid molecules has more order than the gas state. Hope this answers the question.</span>
