Why is being precise important? Precision in scientific investigations is important in order to ensure we are getting the correct results. Since we typically use models or samples to represent something much bigger, small errors may be magnified into large errors during the experiment. Precision is also important in order to ensure our safety. What […]
What is a leeward side of a mountain?
What is a leeward side of a mountain? The opposite side of the mountain is called the leeward side and usually sees much less precipitation. The reason is that air is descending on the leeward side of the mountain, and descending air is warmer and drier, which is the opposite of ascending air. Which side […]
What is the difference between infrared camera and thermal camera?
What is the difference between infrared camera and thermal camera? Active IR systems use short wavelength infrared light to illuminate an area of interest. Some of the infrared energy is reflected back to a camera and interpreted to generate an image. Thermal imaging systems use mid- or long wavelength IR energy. Can an infrared camera […]
Why do Acids burn?
Why do Acids burn? An acid is a substance that separates readily into charged hydrogen ions (H+). These charged ions undergo catalytic reactions named amide/ester hydrolysis, that eventually cause the destruction of proteins and lipids in biological tissue, and therefore the chemical burn. What acid can burn through anything? A common corrosive acid is hydrochloric […]
What is the greatest cause of biodiversity loss?
What is the greatest cause of biodiversity loss? Reason for Loss of Biodiversity Habitat destruction. Habitat destruction is a major cause of biodiversity loss. Invasive Species. Over-exploitation of Species. Global Warming and Climate Change. Pollution. Human Overpopulation. Natural Calamities. Genetic Pollution. What are some impacts of biodiversity loss? Biodiversity loss can have significant direct human […]
How do you calculate weight by age?
What would happen when an electron in AH atom absorbs light?
What happens to a balloon when air pressure decreases?
What happens to a balloon when air pressure decreases? The ideal gas law equation tells us that the pressure of the air in the balloon will increase. As the balloon volume decreases, pressure inside the balloon increases. It eventually is able to balance the outside air pressure. You end up with a balloon filled with […]
Which object will reach terminal velocity first?
Which object will reach terminal velocity first? A falling object will continue to accelerate to higher speeds until they encounter an amount of air resistance that is equal to their weight. Since the 150-kg skydiver weighs more (experiences a greater force of gravity), it will accelerate to higher speeds before reaching a terminal velocity. How […]
Why is energy released in an exothermic reaction?
Why is energy released in an exothermic reaction? Exothermic Reactions In an exothermic reaction, energy is released because the total energy of the products is less than the total energy of the reactants. What is exothermic reaction explain with example? An exothermic reaction is defined as a reaction that releases heat and has a net […]
