Nuclear Energy Pros And Cons
Nuclear energy is a powerful source of energy compared to other conventional fuels. All crude oil based fuels derive their energy from oxidation, which is a change in the energy levels of electrons outside the nucleus. However, nuclear energy derives power from changes in the nuclear energy levels of the atomic nucleus! Tremendous energy lies locked up inside a radioactive nucleus and nuclear fission is a way of tapping this energy. Nuclear power plants derive energy from controlled nuclear fission reactions. This…...

Cooling Rates Of Liquids
Heat energy is conducted from the hot end to the cold end. It is transferred from atom to atom. At the hot end the atoms are vibrating a lot. The vibration is gradually passed along to the other atoms as they collide into each other. This happens in all substances, but in a metal something extra happens. A metal has many free-moving electrons. These free-electrons can travel through the metal, transferring the energy more quickly. Convection: The transfer of energy,…...

Conserving energy is very important because there is a limited amount of nonrenewable energy sources available on earth such as coal, oil, and gas. If people do not conserve the nonrenewable resources we have now, there might not be any left for future generations. In addition, energy conservation is important because when nonrenewable energy sources are consumed this impacts the environment. The combustion of oil, gas, and coal in power stations produces carbon dioxide and contributes to global warming. The…...

Effect Of Air Conditioner On Global Warming
Air Conditioning and Global Warming Air conditioning systems use energy to remove heat from a given location, transferring it to the exterior in the form of exhaust. Some of the energy is invariably wasted as heat, and this additional heat must also be exhausted. Thus, air conditioning results in net heat release to the environment. The warming effect is aggravated, moreover, because higher forms of energy such as electricity are used to power air conditioners. Generating and transmitting this electricity…...
