Question

Which of these statements is justification for the following conclusion: “Right now, there is no way to avoid making pollution when making photovoltaic panels.”

Answer 1

Photovoltaic panel production results in pollution due to the use of hazardous chemicals, the potential harm to habitats where they are installed, and the limitations in substituting traditional energy sources.

Step-by-step explanation:

The statement that photovoltaic panel production inevitably leads to some form of pollution is backed by the following justifications:

1. PV manufacturing involves the use of environmentally unfriendly chemicals and solvents that create hazardous waste.
2. The deployment of PV systems can harm natural habitats especially if they are installed in undeveloped areas, potentially disrupting fragile ecosystems.
3. Finally, all energy is not equivalent or substitutable. While photovoltaic technology is promising, it currently cannot replace fossil fuels entirely due to limitations such as not being able to power airplanes directly with solar PV energy.

These points illustrate the challenges involved in the production and implementation of solar energy technology and underscore that, at present, polluting by-products are an unavoidable aspect of manufacturing photovoltaic panels.

Answer 2

Answer: 1.Think of the English alphabet. Millions of words can be made from only 26 letters! The same thing is true of elements and compounds. Elements are the basic form of matter which cannot be broken down any further. A few common elements make most of the planet’s many compounds. Different compounds combine to make all of the things around us. These include rocks, air, water, and even people.2 Let’s take a trip to Maui in the Hawaiian Islands. You must cross the Pacifi c Ocean. You travel over seawater made of hydrogen, oxygen, sodium, chlorine, and traces of other elements. Pure water has only hydrogen and oxygen. When you get to the island, you walk on the sand. Sand is tiny bits of worn-out rock mostly made of oxygen and silicon. A breeze hits your face. The air is made of nitrogen, oxygen, a little argon, and carbon dioxide. There are also very small amounts of other gases. 3 As you walk around, you see volcanic rocks and mountains on the island. They are made of mixtures of oxygen and silicon, with magnesium, aluminum, potassium, iron, and small amounts of other elements. Green volcanic rock is also common on the island. It has a heavy concentration of iron and magnesium. 4 You also see all the plants and animals. The Hawaiian Islands contain much diversity. You see many beautiful trees, bushes, and fl owers. You see a Hawaiian tree, an orchid on that tree, a beetle crawling on the ground, and a native Hawaiian. These are all examples of living matter made of the elements hydrogen, oxygen, carbon, and nitrogen. Hydrogen is the most abundant element in living matter. 5 As you leave Hawaii, you marvel at what you’ve seen. You are amazed at how so many compounds can be made from so few elements. A few simple elements can combine to make many, many different things.
