Calculate the vapor pressure for a mist of spherical water droplets of radius 3.70×10−8m surrounded by water vapor at 298 K. The

poizon [28]

Answer:

The vapor pressure for a mist is $P= 25.92\ Torr$

Explanation:

From the question we are given that

The radius is $r = 3.70 *10^{-8} m$

The temperature is $T = 298K$

The vapor pressure of water $P_o = 25.2\ Torr$

The density of water is $\rho = 998 kg.m^{-3}$

The surface tension of water is $\sigma = 71.99 m N \cdot m^{-1}$

Generally the equation of that is mathematically represented as

$ln (\frac{P}{P_0} ) = \frac{2 \sigma M}{r \rho RT}$

Where P is the vapor pressure for mist

R is the ideal gas constant = 8.31

making P the subject in the formula

$P = e^ {\frac{2 \sigma M}{r \rho RT}} * P_0$

$= e^{\frac{2 *(0.07199)(0.018)}{(3.70*10^{-8})(998)(8.31)(298)} } * 25.2$

$P= 25.92Torr$

Jupiter is 5.2 times farther from the sun than Earth is. Find Jupiter’s orbital period in Earth years

anzhelika [568]

You can solve this using Kepler's 3rd law. T is proportional to r^1.5. T(J) = T(E)*5.2^1.5 = 11.86 years.
<span>You can also solve it the hard way: Find M (sun's mass) and r(Jupiter's orbital radius) in m. Then use Kepler's equation T = 2pi*r^1.5/sqrt(GM).</span>
