Air Quality And Climate Continued
Bayani Gaba-gaba
The air carries the signs of how we power our world: carbon dioxide that warms the climate, sulfur dioxide and oxides of nitrogen that turn rain acidic. Chemistry not only explains how these pollutants form, it also supplies the solutions, from catalytic converters to low-sulfur fuels and the trees that draw carbon dioxide back out of the air.
In this lesson you will learn the strategies that reduce climate change and acid rain, see how oxides of nitrogen form in car engines and how catalytic converters remove them, and study photosynthesis as the natural reaction that converts carbon dioxide and water into glucose and oxygen.
Manufura
- [Core] State the adverse effect of these air pollutants, limited to: (a) carbon dioxide: higher levels of carbon dioxide leading to increased global warming, which leads to climate change (b) carbon monoxide: toxic gas (c) particulates: increased risk of respiratory problems and cancer (d) methane: higher levels of methane leading to increased global warming, which leads to climate change (e) oxides of nitrogen: acid rain and respiratory problems (f) sulfur dioxide: acid rain
- [Supplement] State and explain strategies to reduce the effects of climate change: (a) planting trees (b) reduction in livestock farming, (c) decreasing use of fossil fuels (d) increasing use of renewable energy, e.g. wind, solar
- [Supplement] State strategies to reduce the effects of acid rain: reducing emissions of sulfur dioxide by using low-sulfur fuels
- [Supplement] Describe how the greenhouse gases carbon dioxide and methane cause global warming, limited to: (a) the absorption, reflection and emission of thermal energy (b) reducing thermal energy loss to space
