Help understanding chemistry (an idea for harnessing energy)

In summary, water molecules rise through evaporation or boiling due to the introduction of heat or air flow, which causes their electrical charge to be attracted to the electrical charge of other molecules in the air. This creates a balloon effect and carries the molecules upward. The process is determined by the amount of energy required to break hydrogen bonds and London forces. As temperature rises, the molecules become more dispersed and can attach to molecules in the air. The ideal gas law also applies, causing water vapor to rise due to its lower density compared to air. However, the removal of water vapor from a closed system is a limiting factor, and the design of a device to achieve this must consider the dew point and contact angle.

Boiling is DIFFERENT than evaporation. Boiling does take energy and vaporizes water quickly.

However, evaporation exists. Same temperature. I'm not sure why you're getting emotional about a physical process, but evaporation happens. So, how does it occur? Well... cohesiveness of water would be the thing to look at. That's determined by the hydrogen bond of hydrogen atoms on that water molecule. How does a water molecule separate from that bond? Well... somehow it is being either repelled or attracted to something else. I've described the process above.

In a system of water & air that is of the same temperature, does evaporation exist?
Answer is of course yes.

Therefore, something is happening at the molecular level that does not require "excitetation" or heat added to the system.
Your understanding of how evaporation works is incorrect...your understanding of why is even worse.

FYI, I make my living designing heating and air conditioning systems, including evaporative cooling systems such as cooling towers. Cooling towers cool water down below ambient temperature by evaporating some of the water to carry off heat. (Your sweaty skin does the same thing on a hot day, by the way). So as a last-ditch effort (that I won't back-check to see if it worked...), please read the wiki on wet bulb temperature, which is a way to measure heat loss due to evaporation: http://en.wikipedia.org/wiki/Wet-bulb_temperature
I've described that process above. Sorry, but your textbooks were incomplete.

What I've described above is the NEW science that replaces chemistry and is called Molecular Dynamics.
Sorry, but as I already said, this is a site for discussing real science only. What you are saying is crackpottery and it is not worth our effort to try to turn you back toward reality. You must choose to do that on your own. If you make that choice, then we can help you make the trip.

OP answered, thread no longer productive, thread locked.

FAQ: Help understanding chemistry (an idea for harnessing energy)

What is the concept behind harnessing energy in chemistry?

The concept behind harnessing energy in chemistry is to use chemical reactions to convert one form of energy into another, more useful form. This can involve breaking and forming bonds between atoms and molecules, resulting in the release or absorption of energy.

How can chemistry be used to generate electricity?

Chemical reactions can be used to generate electricity through a process called electrochemistry. This involves using a redox reaction, where electrons are transferred between two substances, to create a flow of electricity. This is commonly seen in batteries and fuel cells.

What are some examples of renewable energy sources in chemistry?

Renewable energy sources in chemistry include solar energy, wind energy, and biomass energy. Solar energy can be harnessed through photovoltaic cells, which convert sunlight into electricity. Wind energy can be captured through wind turbines, and biomass energy involves converting organic materials such as plants and waste into energy through processes like fermentation and gasification.

How does chemistry play a role in the production of fossil fuels?

Fossil fuels, such as coal, oil, and natural gas, are formed from the remains of plants and animals that lived millions of years ago. These remains undergo chemical reactions over time, resulting in the formation of these fuels. Chemistry is also involved in the extraction and refining processes of these fuels.

Can chemistry help reduce carbon emissions and combat climate change?

Yes, chemistry can play a crucial role in reducing carbon emissions and combating climate change. This can be achieved through the development of cleaner and more efficient energy sources, such as renewable energy technologies, as well as the development of carbon capture and storage technologies to reduce the amount of carbon dioxide released into the atmosphere.
