Can helium be turned into hydrogen to produce energy?
No, energy is produced by the opposite reaction, hydrogen to helium
What is the product of nuclear fusion in the sun?
In the core of the Sun (and other stars) protons (hydrogen nuclei) combine to produce Helium nuclei (alpha particles). In the process, positrons, neutrinos and gamma rays are produced. There are several nuclear reactions that form the steps that go from protons to helium nuclei and the steps impart significant kinetic energy to the products of the reactions. The products of hydrogen fusion are helium, neutrinos, electromagnetic radiation and heat energy.
Does radiation require the presence of particles of matter?
Not necessarily.If you are referring to the spectrum of electromagneticradiation like gamma, X, UV, visible, infra red, thermal,microwave, shortwave, radio/TV waves, they are pureenergy radiation.If you are referring to the radiation emitted by radioactiveelements you have:Alfa radiation. Consists of high energy (kinetic energy)helium nucleus (particles).Beta radiation. High energy (kinetic energy) neutrons (particles).Gamma radiation. Very small wavelength Electromagneticradiation (pure energy).
Can helium be used as a type of energy source?
No. Helium is an inert, non-flammable gas, so it can not be used as an energy source. Hydrogen, however, is a perfect energy source.
Which is universal source of energy?
helium present in stars
If all were at the same temperature how would the average kinetic energy of the particles compare an iron cube an aluminum cube and a balloon filled with helium gas?
If the two metals are at the same temperature then the atoms in each would have the same average kinetic energy. Temperature is a measure of the "average energy per degree of freedom". To simplify things somewhat, kinetic energy is one of these degrees of freedom and so if they have the same temperature they have the same kinetic energy. Go to the related link below for a fuller understanding of the connection between kinetic energy and temperature.
How does the average kinetic energy of the helium atoms in a balloon change as the helium gas is heated?
the theaory of gravity when lifted by a hot air substance is qiute simple if you think about it
What effect does liquid nitrogen have on molecular kinetic energy?
Temperature is a measure of kinetic energy. Because liquid nitrogen is very cold, a system's kinetic energy will be collisionally transferred to the added liquid nitrogen. Thus, in general, adding liquid nitrogen will decrease a system's kinetic energy. (There are some exceptions where the system has less kinetic energy than the liquid nitrogen, such as liquid helium.)
Is Helium a good conducter of energy?
No, nor heat nor electric nor kinetic energy
What happens to kinectic energy in balloon filled with helium gas?
Kinetic energy is lowered as the helium inside becomes compressed. Potential energy is stored, and can be released, usually by popping the balloon.
What is going to happened when a balloon is filled with helium and is left in a car over night temperature drop 20 degrees?
Its volume will be reduced so it will be deflated. As long as there is no leakage, this is due to the fact that the drop in temperature reduces the kinetic energy of the gas atoms, which decreases the collisions between them and the sides of the balloon, which will cause a reduction in the pressure. As long as there is no leakage of the gas, the helium balloon will re-inflate when the temperature increases.
Is helium a liquid at room temperature?
what is the density of helium at room temperature?
What is the temperature of helium at room temperature?
helium is a gas
By what factor does the kinetic energy increase in a container of helium gas is heated from 10 degrees to 100 degrees?
not at all it wont increase period
What has a higher velocity helium or oxygen?
At the same temperature and prssure in a gas the helium atoms will on average move faster than the O2 molecules.
What is helium at room temperature?
Helium is a gas at room temperature.
What is the normal temp for helium?
the temperature for helium is the temperature of the surroundings.
