How much fuel does the sun burn in 1 second? In this way the Sun consumes about 5 billion kilograms (5 million tons) of its nuclear hydrogen fuel every second. How much hydrogen does the sun burn a second? The Sun consumes about 600 million tons of hydrogen per second. (That’s 6 x 108 tons.) […]
What is flux and slag?
What is flux and slag? 1)Flux is the material or substance thats is added to molten metals to bond with impurities that can be readily removed whereas slag is the waste material which is removed. Fluxes are used during the refining of metals. What is slag give example? Slag is waste matter separated from metal […]
Which of the following is the most common cause of a weight loss plateau?
Which of the following is the most common cause of a weight loss plateau? You may need fewer calories or more physical activity to sustain your lower weight. This is the most likely cause of a weight-loss plateau. How is a drug’s plateau reached? It applies whenever a drug or nutrient is infused or ingested […]
What is the relation between pressure and boiling point?
What is the relation between pressure and boiling point? The pressure of gas above a liquid affects the boiling point. In an open system this is called atmospheric pressure. The greater the pressure, the more energy required for liquids to boil, and the higher the boiling point. Why pressure affects boiling point? Pressure Affects the […]
How many valence electrons does magnesium lose to become stable?
How many valence electrons does magnesium lose to become stable? two electrons Does magnesium have 2 valence electrons? The outer energy level for this atom is n = 3, and it has two electrons in this energy level. Therefore, magnesium has two valence electrons. Does magnesium give or take electrons? In ionic molecules, the metal […]
Why is carbon-13 important?
Why is carbon-13 important? The importance of C13 is all the greater because two of the three radioactive isotopes of carbon decay too rapidly to be suitable tracers, while the remaining one (C14) has so long a life (3,000 years) that its detection by radioactive methods is relatively insensitive. How is carbon-13 used? C-13 is […]
Why is water a better moderator than graphite?
Why is water a better moderator than graphite? Water and carbon (graphite) are commonly used moderators. Water is a good moderator, but the hydrogens in the water molecule have a fairly high cross section for neutron capture, removing neutrons from the fission process. Heavy water, used as moderator in Canadian reactors, avoids this loss. What […]
Do superconductors transfer heat?
Do superconductors transfer heat? Metallic wire would introduce heat both by conducting it along its length and by generating heat as the electric current passed through it. A superconducting ceramic, on the other hand, is a poor conductor of heat and a perfect conductor of electricity, so it transmits little heat and produces none. Why […]
Can I reshape my nose without surgery?
Can I reshape my nose without surgery? It’s very unlikely that they’ll have any effect on the shape of your nose. The shape of your nose is primarily determined by your bone and cartilage and can’t be changed without surgery. Can uneven nostrils be fixed? Uneven nostrils can be genetic, a result of trauma, or […]
