What is a contributor of global warming

Chemistry

givi [52]4 years ago

Answer:

Global warming is an effect on our planet that is caused by carbon dioxide being trapped in our atmosphere. When the carbon dioxide is trapped, it is bouncing off the bottom layer of the clouds. Some escapes into outer space, but most of it stays. We cause global warming, by using vehicles, making asphalt, burning fossil fuels, and many more.

An effect of global warming is our poles oceans are melting. When our polar caps melt most of the way, we will experience a lot of flooding for many coastal cities. We will also experience extreme weather, like stronger hurricanes, larger thunderstorms, and larger areas effected by other natural disasters.

One thing we can do to stop or slow down these effects is to use vehicles less (or make better vehicles for the environment), stop burning fossil fuels, and make a world-wide law to prevent certain things from commencing. Nuclear bombs are also a problem to global warming. We will hopefully never reach that problem.

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.
