Photovoltaic Electricity Photovoltaic (PV) electricity is a type of solar energy that converts sunlight into electricity using semiconductors. PV cells are made of materials that allow electricity to flow when light hits them. When sunlight hits a PV cell, it knocks electrons loose from their atoms. These free electrons flow through the cell, creating an … Read more

Measures to control acid rain Acid rain is a serious environmental problem that has been affecting the planet for decades. It is caused by the release of sulfur dioxide and nitrogen oxides into the atmosphere, which react with water vapor to form sulfuric and nitric acids. These acids then fall back to Earth as rain, … Read more
What is acid rain? Acid rain is a form of precipitation that is highly acidic, meaning that it has a low pH. The pH scale ranges from 0 to 14, with 7 being neutral. Anything below 7 is considered acidic, and anything above 7 is considered alkaline. The pH of normal rain is about 5.6, … Read more
Difference between normal and anthropogenic acidified lakes Acidification of lakes is a serious environmental problem that can have a devastating impact on aquatic ecosystems. There are two main types of lake acidification: natural and anthropogenic. Subscribe on YouTube Natural acidification occurs when rainwater reacts with minerals in the soil and rocks, releasing acids into the … Read more
Characteristics of Acid Rain Acid rain is a form of precipitation that is acidic, meaning that it has a pH below 7.0. The pH scale ranges from 0 to 14, with 7 being neutral. A pH below 7 is acidic, and a pH above 7 is alkaline. Acid rain is caused by the emission of … Read more
Sources of Compounds Causing Acid Rain Acid rain is a form of precipitation that is more acidic than normal rain. It is caused by the emission of sulfur dioxide and nitrogen oxides into the atmosphere, which react with water vapor to form sulfuric acid and nitric acid. These acids then fall to the ground as … Read more
