Predict the gravitational and electrostatic forces between molecules of gases? Provide evidence for your prediction.
zmey [24]

the electrostatic forces are 10^{36} larger than the gravitational force

Explanation:

Let's do the calculation by using two molecules of hydrogen, each containing 2 atoms of hydrogen.

The gravitational force between the two molecules is given by:

F=\frac{G m_1 m_2}{r^2}

where

G=6.67\cdot 10^{-11} m^3 kg^{-1}s^{-2} is the gravitational constant

m1 and m2 are the masses of the two molecules: since they are identical,

m_1 = m_2 = 2m_p = 1.67\cdot 10^{-27} kg, twice the mass of the proton

r is the distance between the two  molecules

The force can be rewritten as

F_G=\frac{Gm_p^2}{r^2}

We can assume instead that electrostatic force between the two molecules is given by the interaction between the positively charged nuclei and the neatively charged electrons. Therefore,

F_E=\frac{kq_1 q_2}{r^2}

where

k=8.99\cdot 10^9 Nm^{-2}C^{-2} is the Coulomb's constant

q_1 = q_2 = 2e is the magnitude of the charge of each molecule, where

e=1.6\cdot 10^{-19}C is the fundamental charge

r is the distance between the two molecules

So the force can be  rewritten as

F_E=\frac{ke^2}{r^2}

Therefore, the ratio between the two forces is:

\frac{F_E}{F_G}=\frac{ke^2}{Gm_p^2}=\frac{(8.99\cdot 10^9)(1.6\cdot 10^{-19})^2}{(6.67\cdot 10^{-11})(1.67\cdot 10^{-27})^2}\sim 10^{36}

So, the electrostatic forces are 10^{36} larger than the gravitational force.

Why does heating increase the speed at which a solute dissolves in water?
aivan3 [116]
For many solids dissolved in liquid water, the solubilityincreases with temperature. Theincrease in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.
