What is fusion as opposed to fission and why does it need high temperatures and fast speeds?
Fusion is putting together (atoms ... usually hydrogen atoms),
Fission is the breaking apart of atoms.
And fusion requires high energy to occur because it requires the nucleus of atoms to touch (collide) - not an easy thing to do (basically impossible using only chemical energy).
What else can I help you with?
Why would gases diffuse faster on a warm day than on a cold day?
The molecules of a gas move faster at higher temperatures, which therefore speeds up diffusion.
Observations that deal with a number or amount are called what?
Quantative or Quantifiable Measurements. You can take some measure and get a number out. Length, Temperature, Area etc. As opposed to Qualititive Measure - Happiness, anger etc you can't take a ruler to someones mood.
Is the roadrunner an fast animal?
A road runner can run speeds up to 17 mph.
Kepler's equal area law implies that when a planet gets closer to the sunit?
speeds up
How does the presence of myelin help axons work?
Myelin makes it easier for acons to transmit signals- it speeds there work.
Where does a fusion take place in the sun?
The core or the sun's photosphere.
Hydrogen nuclei collide at high speeds to form helium nuclei this reaction is called?
Fusion
Does a particle accelerator used to accelerate particles at high speeds until the particles fuse together and create a new element?
A particle accelerator used to accelerate particles at high speeds will not fuse together and create a new element. The particle accelerator uses electromagnetic fields to move charged particles and contain them in well defined beams.
What is the name of the reaction when hydrogen nuclei collide at high speeds to form helium nuclei?
It's a nuclear fusion reaction
Why must an extremely high energy level be reached before a fusion reaction can take place?
Fusion occurs because two nuclei are colliding to create a new nucleus. Because the atoms are positively charged, they naturally repel each other, so high amounts of energy are required to counter-act this force.
What type of reaction is synthesis?
photosynthesis is the reaction that takes place in which plants turn CO2 and water (H20) in the presence of sunlight into glucose (C6H1206) and oxygen
Why doesn't a gas particle move at the same speed as all temperatures?
Gas particles move at different speeds due to their kinetic energy, which is related to the temperature of the gas. At higher temperatures, gas particles have more kinetic energy and move faster on average, leading to a range of speeds rather than all particles moving at the same speed. This distribution of speeds is described by the Maxwell-Boltzmann distribution.
What is energy from high temperatures?
High temperature speeds up movement in the molecules. This means with higher temperature, there is more energy
What is the main limitation of an IDE?
At this point in technology. It would be Bulkier Cabling. Which means worse Air Flow and hotter temperatures. Slower Speeds
Why does fusion reactions do not occur naturally on earth but do in the sun?
The conditions at the sun's core give very high pressure due to the gravitational forces, and also a high enough temperature. The earth isn't big enough to produce these conditions, and in any case is mostly made of heavy materials which would not undergo fusion. Efforts to make fusion on earth are using the two materials deuterium and tritium which have the lowest threshold conditions for fusion to start, but even so it is necessary to achieve higher temperatures than even on the sun to make a feasible power plant. In fact fusion on the sun has a surprisingly low power density, and a plant operating at those conditions would have to be huge to produce any useful power. Nothing achieved yet on earth has produced more power output than the input, but development continues and hopefully a solution will eventually be found. If not, mankind will run out of power (but not in our lifetimes).
What is the speed of nuclear fission?
In an atomic bomb the time between fission generations is about 10ns and the entire reaction is over in 1us to 3us. In an atomic reactor the time between fission generations is about 10us because each neutron must collide about 1000 times with moderator atoms to slow down to "thermal" speeds.
Where can one download SpeedFan?
SpeedFan is a free program that monitors and shows fan speeds, voltages and computer temperatures. It can be downloaded through the creator's website or CNET.
