Which two gases Cannot be broken down by chemical means? Answer Expert Verified The answer is (2) CO and NH3. The chemical reaction can only break down chemical bonds between atoms inside the molecule. The He and Xe is consists of one atom only, so they can not be broken down by chemical means. Which […]
Which is heavier 1kg gold or 1kg cotton?
What is difference between gauge and absolute pressure?
What is difference between gauge and absolute pressure? The simplest way to explain the difference between the two is that absolute pressure uses absolute zero as its zero point, while gauge pressure uses atmospheric pressure as its zero point. Due to varying atmospheric pressure, gauge pressure measurement is not precise, while absolute pressure is always […]
Why are heat engines so terribly inefficient?
Why are heat engines so terribly inefficient? But yes, heat engines are generally quite inefficient. Ultimately, it’s because heat itself is a fairly inaccessible form of energy. Doing that removes energy from the gas so it cools and loses pressure. By repeating the compression of a hot gas and extracting energy using a piston, we […]
Are humans carnivores?
Are humans carnivores? Humans are definitely omnivores. The best evidence is our teeth: we have biting/tearing/ripping incisors and canines (like carnivores) and chewing molars (like herbivores). Animals with such diverse teeth tend to be omnivores. Can a human live without meat? As a new study in Nature makes clear, not only did processing and eating […]
What happens when an electron returns to a lower level?
What happens when an electron returns to a lower level? When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level. The energy of the photon is the exact energy that is lost by the […]
What is Jar Voltage?
What is Jar Voltage? A constant power discharge occurs when the load current is increased during the discharge by an amount proportional to the normal decline in battery voltage. Often refered to as a jar. Who created the Leyden jar? Pieter van Musschenbroek How are the charges distributed across the Leyden jar? When electricity goes […]
What is Uniformitarianism Lyell?
What is Uniformitarianism Lyell? Uniformitarianism is a theory based on the work of James Hutton and made popular by Charles Lyell in the 19th century. This theory states that the forces and processes observable at earth’s surface are the same that have shaped earth’s landscape throughout natural history. What is the difference between uniformitarianism and […]
What happens when an electron jumps from energy level 3 to 7?
How many rainbows can you see at once?
How many rainbows can you see at once? four Can Moonlight make a rainbow? The moon can create rainbows if the light reflected is bright enough and there’s sufficient moisture in the right spot in our atmosphere. Fogbows can form overnight if there’s enough moonlight and moisture in the air. Where do you look for […]
