The pressure of air in your house can stay constant during the day if the temperature rises. let the temperatures be 295 k during the day, and 288 k at night, and volume of the house be 900 m3. part a determine the number of moles of air that leave the house during the daytime.

N = 903.73 moles

Explanation:

The pressures are constant so:

V1/T1 = V2/T2

During the night, V1 = 900 m^3, and T1 = 288K.  

During the day, T2 = 296K, and V2 =?

V2 = V1*T2/T1 = 900*295/288 = 921.875 m^3

921.875 - 900 = 21.875 m^3

that leave the house during the daytime

V2/T2 = Vs/Ts

Vs = V2*Ts/T2 = 21.875*273/295 = 20.24 m^3

22.24 liters per mole, and 1000 liters per m^3, so

N = 20.24*1000/22.4

N = 903.73 moles.

i do.

explanation:

i want to explore the wonders of the universe and find out if there really is life out there. i think the universe is beautiful.
