Why is carbon monoxide especially dangerous? Why are crystalline solids brittle? Why is thermal stratification important? Why is methane a stronger greenhouse gas than carbon dioxide? Why are alveoli so small? Why is carbon monoxide an air pollutant?
Why is carbon dioxide more soluble than oxygen? Dipoles: Dipoles are formed when a covalent bond contains atoms with significantly different electronegativities. This results in a greater electron density around the more electronegative element, resulting in a partial negative charge on that element an...
Carbon monoxide is a very harmful gas because it combines with the haemoglobin of blood to form carboxyhaemoglobin which is unable to transport oxygen. As a result, the body becomes oxygen starved. At 100 ppm concentration in air, it causes giddiness and
Hopefully, we will find that CDR is actually a source of economic acceleration. I want to be very careful about predicting what the technology is going to look like in 30 years. That’s dangerous. But at the same time, technologies tend to deliver much higher ...
Why is smog unhealthy? Photochemical smog is dangerous because of the mix of pollutants it holds, many of which are known to have adverse health effects. Most symptoms of smog exposure are short-term, meaning they should go away within a few hours or days of exposure. However, repeated dama...
"The main cause of rapid global warming today is heat-trapping pollution from human activities," the group explains. "...This year's record global average temperatures reflect extreme and often dangerous heat events driven by human-caused climate change." ...
We've all seen our scientists explaining what global warming is, why it's dangerous, and what we can do to stop it. We put the blame on fossil fuels and auto emissions(排放).But the meat industry is often unnoticed as a major cause, which produces more greenhouse gases than all the ...
Biodiversity is necessary for all living things,including humans.However,it is dangerous because of human activities such as deforestation(毁林),pollution,and climate change. One of the main reasons why biodiversity is important is that it provides us with many necessary ecosystem...
Polluted air and steadily rising temperatures are linked to health effects ranging from increased heart attacks and strokes to the spread of infectious diseases and psychological trauma.
Of course air travel contributes to climate change because planes burn fossil fuels to fly and add carbon dioxide into the air. But the thermal effect of contrails is a separate phenomenon, distinct from aviation’s greenhouse gas emissions. And it’s a surprisingly potent impact. “The contr...
