Angles 1 and 2 are supplementary. 2 lines intersect to form angles 1 and 2. Which equation represents the relationship between their measures? mAngle1 mAngle2 = 90° mAngle1 mAngle2 = 100° mAngle1 mAngle2 = 180° mAngle1 mAngle2 = 200°

1.25 cm/day

Explanation:

An air thickness , (l) = 0.15 cm

Air Temperature =

Mass Diffusion coefficient (D) =

If the air pressure

We are to determine how fast will the water level drop in a day.

From the property of air  at T = 20° C

from saturated water properties.

The mass flow of  can be calculated as:

where:

R(constant) = 8.314 kJ/mol.K

Since 1 mole = 18 cm ³ of water

will be:

Again:

Converting the above value to cm/day: we have:

= 1.25 cm/day

∴ the rate at which  the water level drop in a day = 1.25 cm/day
