A prime example of man-made nuclear energy is the generation of electricity. A prime example of natural nuclear energy is the nuclear reactions the sun produces to create heat and light. Nuclear energy involves a process called “fusion.”Know More
Fusion involves the collision of atomic nuclei, an event that creates a tremendous amount of heat. In generating electricity, for instance, the heat created by fusion warms water to the boiling point, which releases steam. This steam powers turbines that create electricity.
In the core of the sun, the heat and pressure are extreme enough to create the fusion needed to unleash its natural nuclear energy. Less than 8 percent of the energy needs in the United States are met via nuclear energy, according to the U.S. Department of Energy. Petroleum, natural gas and coal are the primary energy resources in the United States and many other countries around the globe.Learn more about Earth Science
Geothermal energy is used to supply heat for industrial purposes. It may also be used to promote agricultural and aquaculture production in cold climates by heating soils, aquaculture ponds and greenhouses. In addition, high-temperature geothermal energy is used to generate electricity.Full Answer >
Thermal energy moves from one object to another through heat energy. Heat energy moves through convection, conduction and radiation. The internal movement of atoms generates energy in matter. As the temperature of matter increases, the internal movement also increases.Full Answer >
The primary heat source for the Earth is the radioactive decay of uranium, thorium and potassium, found in the mantle and crust. The Earth produces more heat through phase changes, such as the freezing of liquid iron in the inner core and minerals in other parts of its core. In addition, the slow cooling process of the Earth gives off heat that melts magma.Full Answer >
An example of a high specific heat is water’s specific heat, which requires 4.184 joules of heat to increase the temperature of 1 gram of water 1 degree Celsius. Scientifically, water’s specific heat is written as: 1 calorie/gm °C = 4.186 J/gm °C.Full Answer >
