specinho + 470 January 2 9 hours ago, turbguy said: To elaborate, ask yourself this question... "What happen to the internal temperature of a system when the incoming heat is IMBALANCED by a reduction of the outgoing heat" Sublimation of solid co2 happens at -78.5'C. At ~4'C, the pressure of gas co2 in a container is ~41 bar. Yet, pressure required for gas co2 to form solid or dry ice is ~ 5 bar. Hence, shall you increase temperature of gas co2 in a container, it turns into solid. In addition, the first image shows frequency absorbed by co2 does not constitute heat. Combining both, the conclusion and deduction would be: 1. Co2 does not absorb heat 2. Increase temperature in a container will increase pressure and turn gas co2 into solid? 1 Quote Share this post Link to post Share on other sites

Vibrating faster is the definition of increase in temperature. https://en.wikipedia.org/wiki/Temperature "Temperature is measured with a thermometer. It reflects the kinetic energy of the vibrating and colliding atoms making up a substance." Also increase in volume at the same pressure is a increase in temperature by the ideal gas law PV=nRT V= nRT/P Clearly a change in volume is proportional to the change in temperature. R, P and n are held constant. Do the math ya little n@zi. 👆Kindly refer reply above to turbguy. There are people who oppress, torture or bully because they say they can and they want to.

"Frequencies" is one thing. "Power" contained within those frequencies is another. Integrate. Also, these are called phase diagrams. This one is for CO₂ (approximately).

My friend it is you that is missing the point Until post war the amount of FF burnt was insignificant, since then with population increases and increased demand for heating + aircon, has sky rocketed! Hell aircon wasnt even a thing until the 1960's By the 1960s, most new homes in the United States were built with central air conditioning. By then, electric air conditioner window units were affordable and had come down in price from the early days; a 1938 Chrysler unit cost $416. 1 Quote Share this post Link to post Share on other sites

It dissolves mildly in water to form weak acid. Mildly not equals to " very reactive". Clearly you didn't read my post (inductive effects). I straight out told you, in advance, what your crappy rebuttal was going to be. Read it again, out loud if that helps. Here it is: "CO2 is non polar in isolation in gas phase. However, it is highly polar inter-molecularity with the carbon in the +4 oxidation state and the two oxygens at -2. The strong partial positive charge on the the carbon makes it very reactive and polar when it interacts with other molecules." If you had looked at the vibrational rotational spectroscopy page you would have clearly seen that they have the CO2 spectra listed. Just FYI there are also induced dipoles. https://en.wikipedia.org/wiki/London_dispersion_force If you want to discuss how symmetric a molecule is we use specific terminology. https://en.wikipedia.org/wiki/Symmetry_group I could teach you a whole degree in chemistry if you actually read the material and had the mental capacity. We would have to start near grade school if you can't understand photosynthesis. I'll make this simple. CO2 is so reactive that you if mix it with some water, light, and some fancy catalysts you get food. Edited January 5 by TailingsPond Quote Share this post Link to post Share on other sites

Better said world wide trade...Interesting topic..just who owns those tanker fleets, How 16 ships create as much pollution as all the cars in the world Bunker fuel is also thick with sulphur. IMO rules allow ships to burn fuel containing up to 4.5 per cent sulphur. That is 4,500 times more than is allowed in car fuel in the European Union. The sulphur comes out of ship funnels as tiny particles, and it is these that get deep into lungs. Thanks to the IMO’s rules, the largest ships can each emit as much as 5,000 tons of sulphur in a year – the same as 50million typical cars, each emitting an average of 100 grams of sulphur a year. With an estimated 800million cars driving around the planet, that means 16 super-ships can emit as much sulphur as the world fleet of cars. https://www.dailymail.co.uk/sciencetech/article-1229857/How-16-ships-create-pollution-cars-world.html Only to be compounded....it's time these offending nations to pay the Sulfur Tax...say goodbye to the Paris accords... A Shipping Rule Backfires, Diverting Sulfur Emissions From the Air to the Ocean https://insideclimatenews.org/news/17072023/ship-scrubbers-water-pollution/ World fleet development and composition In January 2023, the world’s merchant fleet consisted of 105 500 vessels of at least 100 gross tons (gt), of which 56 500 ships were over 1000 gt. Of the ships built in 2022, in gross tonnage terms, 93 per cent were completed in China, the Republic of Korea or Japan. Ship recycling happened predominately in India, Bangladesh or Pakistan. These economies jointly accounted for 86 per cent of ships recycled (on a gt basis). The world fleet reached a carrying capacity of 2.3 billion dead weight tons (dwt) in January 2023, 70 million dwt more than a year ago. Oil tankers, bulk carriers, and container ships accounted for 85 per cent of total capacity. World fleet capacity has expanded at varying rates over time. Growth in dwt averaged a firm annual 7.1 per cent between 2005 and 2010. Reflecting a consolidation in shipbuilding capacity and a downsizing of the ship financing market, the average annual growth has decelerated to 4.1 per cent per year since 2010.
