Similarities between thermal and nuclear power plant (at least half page) |
|
Answer» Nuclear power plant- A nuclear power plant is a type of power station that generates electricity using heat from nuclear reactions. These reactions take place within a reactor. The plant also has machines which remove heat from the reactor to operate a steam TURBINE and generator to make electricity. Electricity made by nuclear power plants is called nuclear power. Nuclear power plants are USUALLY near water to remove the heat the reactor MAKES. Some nuclear power plants use cooling towers to do this. Nuclear power plants use uranium as fuel. When the reactor is on, uranium atoms inside the reactor split into two smaller atoms. When uranium atoms split, they give off a large amount of heat. This splitting of atoms is called fission. The most popular atoms to fission are uranium and plutonium. Those atoms are slightly radioactive. The atoms produced when fuel atoms break apart are strongly radioactive. Today, fission only happens in nuclear reactors. In nuclear reactors, fission only happens when the reactors parts are arranged properly. Nuclear power plants turn their reactors off when replacing old nuclear fuel with new fuel. There are about four hundred nuclear power plants in the world, with many in the United States, France, and Japan. Some famous accidents at nuclear power plants were the 2011 Fukushima nuclear disaster in Japan, 1986 Chernobyl disaster in Ukraine, and the 1979 Three Mile Island accident in the United States. There has been a recent debate about installing a nuclear power plant within Australia many people do not want this and many do want it, its been a highly controversial debate in the country. Thermal power station- A thermal power station is a power station in which heat energy is converted to electric power. In most of the places in the world the turbine is steam-driven. Water is heated, turns into steam and spins a steam turbine which DRIVES an electrical generator. After it passes through the turbine, the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle. The greatest VARIATION in the design of thermal power stations is due to the different heat sources; fossil fuel dominates here, although nuclear heat energy and solar heat energy are also used. Some prefer to use the term energy center because such facilities convert forms of heat energy into electrical energy.[1] Certain thermal power stations are also designed to produce heat energy for industrial purposes, or district heating, or desalination of water, in addition to generating electrical power. |

How to find the hydrogen concentration |
|
Answer» I hate writing LONG ANSWERS like others do for upvotes.*It’s Hydromium ion not hydrogen ion. Right? PH formula is always used for hydromium ion.Well I assume you know what is pH. If not then you can ask me. the formula ispH= -LOG [H3O+]if you are given the pH then you do the log inverse on both sides of the equation.So if you are given a pH of 3, then you will do the following:-3= -log[H3O+]When you multiply both sided by -1, then you will get,-3= log[H3O+]log inverse is to raise -3 to the base 10.10^-3 = [H3O+]0.001 = [H3O+]So in this case pH of hydromium ion is 0.001 M |

What is the difference between male and female Pinus? |
|
Answer» A female pine cone, also called a megasporangiate strobilus, consists of cone or seed scales that hold two ovules, the unfertilized seeds. It takes about two years for female pine cones to become mature. When the seed matures, the cone opens up, exposing the seeds to the environment. Once the seeds are mature, the seed scales fall out of the cone. Seeds are then carried away from the parent TREE by the wind and animals. Some female pine cones do not open up until they experience high temperatures such as during a forest fire. |
