i don't really know the answer
The model of the atom has dramatically changed over many many years.We learned atoms make up different substances and are the smallest particles of matter, which have subatomic particles that are very small portions of matter. At first scientist only thought there were electrons which are negatively charged.
They are odourless, colourless monatomic gases with full outer shells
Explanation:
Relation between pressure of water and its droplet is as follows.
where, p = pressure of droplet
= water pressure in given temperature
=
M = Molecular Weight in Kg/Mol (0.018 for water)
r = radius in meters
= density of water in
(1000
)
R = ideal gas constant (8.31)
T = temperature in Kelvin
(a)
We will calculate the value of p as follows.
p =
=
= 26.8 torr
(b) And, vapor pressure of spherical water droplets of radius 2.0
or 
p =
=
= 25.2 torr
