What happens to pressure if volume decreases in gas? Explanation: Gas particles exert pressure by colliding with the walls of their container. If you reduce the volume, you are effectively increasing the density of the particles and they will collide with the walls more frequently, leading to an increase in pressure. Why does the volume […]
Why are top predators so rare?
Why are top predators so rare? This energy constraint is the fundamental reason top predators are so rare. Many food webs consist of half a dozen or more trophic levels, and by the time you get to the top, there’s simply not that much energy left. It’s their naturally small populations that also leave these […]
Should a fridge be on its own breaker?
Should a fridge be on its own breaker? Do Refrigerators Need Dedicated Circuits? Having the refrigerator on its own dedicated circuit is the recommended best practice for homeowners. Most refrigerators run between 3 to 6 amps, with that said, a refrigerator can spike at peak usage up to 15 amps. What does circuit breaker protect […]
Can nuclear waste be destroyed?
Can nuclear waste be destroyed? It can be done. Long-term nuclear waste can be “burned up” in the thorium reactor to become much more manageable. Where does nuclear waste go? More than a quarter million metric tons of highly radioactive waste sits in storage near nuclear power plants and weapons production facilities worldwide, with over […]
What is an example of nuclear potential energy?
What is an example of nuclear potential energy? Example: Nuclear fission, nuclear fusion, and nuclear decay are examples of nuclear energy. An atomic detonation or power from a nuclear plant are specific examples of this type of energy. Where is nuclear energy used? Top five nuclear electricity generation countries, 2019 Country Nuclear electricity generation capacity […]
Where is most energy found in a food web?
Where is most energy found in a food web? The vast majority of energy in food webs originates from the sun. Energy is not recycled in ecosystems and each ecosystem requires a continuous input of energy to sustain it. There is some energy transformed at each level of the food chain or food web in […]
Is it better to drive fast or slow through water?
Why do divers exhale when surfacing?
Why do divers exhale when surfacing? As the diver ascends, the air in the lungs expands as surrounding water pressure decreases. Exhaling allows excess volume to escape from the lungs, and by exhaling at a suitable rate the diver can continue exhaling throughout the ascent and still have air in his or her lungs at […]
What does access only mean?
What does access only mean? An ‘access-only’ road or street is that has a ban on motor traffic using it, except for access. The intention is to allow cycles (and people walking) to use the road as a through-route, while limiting motor traffic to just those vehicles accessing properties. What does this sign mean at […]
What are the 4 properties of atom?
What are the 4 properties of atom? Chemical properties Atomic number. The atomic number indicates the number of protons within the core of an atom. Atomic mass. The name indicates the mass of an atom, expressed in atomic mass units (amu). Electronegativity according to Pauling. Density. Melting point. Boiling point. Vanderwaals radius. Ionic radius. Do […]
