What can we use instead of crude oil? Alternative energy sources are substitutes for crude oil. These Crude Oil Substitutes include: solar energy, oil sands, wind power, coal mine methane, geothermal energy, nuclear energy, LNG, hydrogen fuel cells, and natural gas.. Energy efficiency improvements should also count as alternative energy sources. How can alternative energy […]

What is the difference between global warming and the green house effect? Global warming is the change in the climate of the earth causing it to heat up whereas the greenhouse effect is a naturally occurring phenomena, constantly occurring due to the atmosphere and sunlight. This heat is trapped by some of the greenhouse gases […]

What is causing the glaciers in Glacier National Park to melt? The retreat has happened as temperatures in the region have risen by 1.5°F since 1895 as heat-trapping greenhouse gases have continued to accumulate in the atmosphere. A 2014 study found that it is this human-caused warming that accounts for the bulk of worldwide glacier […]

How does liquid ventilation work? Liquid ventilation (LV) is a technique of mechanical ventilation in which the lungs are insufflated with an oxygenated perfluorochemical liquid rather than an oxygen-containing gas mixture. What is partial liquid ventilation? Partial liquid ventilation, also known as perfluorocarbon-associated gas exchange, is a modified approach in which perfluorocarbon liquid is instilled […]

When baking soda is heated it releases carbon dioxide? When baking soda (sodium bicarbonate or sodium hydrogen carbonate,;NaHCO3) is heated, it releases carbon dioxide gas, which is responsible for the rising of cookies, doughnuts, and bread. When baking soda is heated sodium carbonate water and carbon dioxide gas are formed? Sodium hydrogen carbonate (also known […]

What is the smallest component of an animal cell? Ribosomes Why are cells the smallest living thing? Cells make up the smallest level of a living organism such as yourself and other living things. The cellular level of an organism is where the metabolic processes occur that keep the organism alive. That is why the […]

What effect does changing the concentration have on the pH value? In general, the pH of an acid solution will be lower as the solution is more concentrated. For bases, the pH will be higher with more highly concentrated solutions. Does increasing concentration increase pH? As a solution gets more basic (higher [OH-]), the pH […]

What does a spectrometer do? A spectrometer measures the wavelength and frequency of light, and allows us to identify and analyse the atoms in a sample we place within it. What parts of the electromagnetic spectrum can spectroscopy be performed? Spectroscopy can detect a much wider region of the EM spectrum than the visible wavelength […]

What causes osteoporosis? A lifelong lack of calcium plays a role in the development of osteoporosis. Low calcium intake contributes to diminished bone density, early bone loss and an increased risk of fractures. Eating disorders. Severely restricting food intake and being underweight weakens bone in both men and women. Is osteoporosis a genetic or age […]

What happens when the electron moves from the first energy level to the second energy level? Answer: When the electron moves from the first energy level to the second energy level, energy is absorbed. Explanation: When an electron moves from first energy level to the second energy level,energy is being absorbed by the atom which […]
