When a gas changes into a liquid, it is called condensation. ... When a liquid changes into gas, it is called evaporation. Phase changes are usually caused by changes in temperature or pressure. As the states of matter change from solid to liquid to gas, respectively, their composition changes as well.
Answer:
They include: Chemical nature of the pollutant - how active and toxic it is to humans, plants and animals; Concentration - the amount of the chemical per unit volume of air, water, soil, and; Persistence or longevity - how long the pollutant remains in the environment in its harmful form.
Explanation:
Air pollutants like ozone, particulate matter, carbon monoxide, nitrogen oxide, sulfur dioxide, lead cause atmospheric pollution which regards to ozone depletion, GH effect, climate change and human health effects. If anyone say the main factors of air pollution beyond of industry, means of transportation, solid waste generation and urbanization.
Growing urbanization and industrialization grows more pollution. Due to a large number of population in the world, more pollution is generated. Specifically if we talk about air pollution, due to steady increase in number of industries, the gradient level is deteriorating day by day. There is no good if we just talk about sustainable development if we are not following it.
Answer:
Fluorine is identified as the most reactive nonmetal and the most electro-negative element in the periodic table, making it the strongest oxidizing agent. Caesium is the most reactive metal in the periodic table, so much that working with this metal often ends in explosions!
Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.
Hope that helps.
