Only indirectly ... via the sun.
No.
Neither, because the earth's centre is composed of heavy materials not hydrogen. This is really a topic for earth scientists rather than nuclear ones, but my understanding is that the earth's heat comes from radioactive decay and residual heat from when the earth was formed, but no-one really knows all the answers.
When alkali earth metals react with water, they produce metal hydroxides and hydrogen gas. The reaction is generally violent and releases heat.
Heat it.
The sun generates heat and light through nuclear fusion in its core. This fusion process converts hydrogen into helium, releasing vast amounts of energy in the form of heat and light. This energy is then radiated out as sunlight, which warms the Earth.
The Sun produces heat through a process called nuclear fusion, where hydrogen atoms in its core combine to form helium, releasing vast amounts of energy in the form of heat and light. This process generates temperatures of millions of degrees, resulting in the Sun emitting heat and light that reaches the Earth.
The heat from the sun is generated by nuclear fusion in its core, where hydrogen atoms are converted into helium. This heat is then radiated out into space in the form of sunlight, warming our planet and providing the energy that drives Earth's climate and weather systems.
Hydrogen is a poor conductor of heat and electricity. As a gas, it does not have free-moving electrons to conduct electricity. In terms of heat, hydrogen has low thermal conductivity compared to metals.
When hydrogen peroxide is exposed to light or heat, it decomposes into water and oxygen gas.
The sun gives off heat through a process called nuclear fusion, where hydrogen atoms combine to form helium, releasing energy in the form of heat and light. The high temperatures and pressures at the sun's core are necessary for this nuclear fusion to occur, resulting in the immense heat and energy that we feel on Earth.
The only pure hydrogen is found in the atmosphere as H2. Under the ground are many compounds containing hydrogen such as methane gas and water.
A star, like the sun, spends much of its life producing energy, in the form of light and heat, through the fusion of hydrogen into helium. When the hydrogen is mostly used up the star moves to fusion of helium into larger (heavier) elements. At that stage the sun will become a red giant. It will then be large enough to engulf the earth's orbit, thyough well before that happens, the earth will be a burnt, lifeless "cinder".
