The surface tension of water in air is approximately 0.00518 lbf/ft. if the atmospheric pressure is 14.7psia, what is the pressu

strojnjashka [21]

Based on the calculations, the pressure inside this droplet is equal to 2,909.35 kPa.

<u>Given the following data:</u>

Surface tension = 0.00518 lbf/ft to N/m = 0.00702 N/m.

Atmospheric pressure = 14.7psia to kPa = 101.35 kPa.

Diameter = 0.01 mm to m = 0.00001 m.

Radius, r = $\frac{diamter}{2} =\frac{0.0001}{2}$ = 0.000005 m.

<h3>How to determine the pressure inside a droplet.</h3>

For a droplet with only one surface, its pressure is given by this formula:

$P_1-P_2=\frac{2 \tau}{r} \\\\P_1=\frac{2 \tau}{r}+P_2$

Substituting the given parameters into the formula, we have;

$P_1=\frac{2 \times 0.00702}{0.000005} + 101.35\\\\P_1=2808+ 101.35$

Inside pressure = 2,909.35 kPa.

natita [175]

Answer:

See explanation

Explanation:

When an element tends to lose its valence electrons in chemical reactions, it behaves more like a metal.

When an element tends to gain valence electrons in chemical reactions, it behaves more like a nonmetal.

Metalloids have properties intermediate between those of pure metals and pure nonmetals. Usually, metalloids appear in groups where they are sandwiched between nonmetals and metals such as in groups 13, 14 and 15.
