What is the term for rock containing a metal or other useful mineral that can be mined and sold at a profit?
Rock material mined for its constituent elements or minerals is called "ore."
What is the coldest material on earth?
- for a natural material: a stone from Antarctic- for a manmade material: solid helium
How is heat made from the core?
The inner core of the Earth is believed to be composed of iron and nickel, with a dash of other heavy metals. Several of these are radioactive, and this fission creates heat. Studying seismic waves that have travelled through the core, gives us data and it from this that the above interpretation is made. The inner core is thought to be solid on account of the extremely high pressures. Surrounding this is the outer core, which is at roughly the same temperature (because of conduction), but under less pressure, is liquid. From this material the volcanic magma comes. Eventually, the radioactive core will cool down, the volcanoes will cease, and Plate Tectonics will draw to a halt.
What is a material that conducts electric current slowly?
Material with high resistance
What is the duration of Material Girls?
The duration of Material Girls is 1.62 hours.
What is an autoradiograph?
An autoradiograph is a photographic image produced by placing a film in contact with a specimen containing radioactive material.
What is the bullet in a fission reaction?
An electron is fired into the reactor core containing the radioactive material, usually uranium, and as it hits the radioactive nucleus the uranium atom breaks down forming two daughter nuclei and emitting another electron (beta radiation particle) which continues as a chain reaction.
When a material goes through radioactive decay there is a new daughter product in the solid material so can this new daughter material react chemically with the rest of the solid matrix around it?
Yes, the daughter product resulting from radioactive decay can potentially react chemically with the surrounding solid matrix. This reaction may depend on the properties of the daughter product and the matrix material. It is important to consider these interactions when assessing the behavior of radioactive materials in a solid matrix.
What is it called when an unwanted material that contains radioactive atoms is present on another material?
It is called contamination when an unwanted material containing radioactive atoms is present on another material. Contamination can occur through direct contact, airborne transfer, or ingestion of the radioactive material. It is important to address contamination promptly to minimize exposure and potential health risks.
What are radioactive pellets?
Radioactive pellets are small, sealed capsules containing radioactive material. They are often used in medical treatments for conditions like cancer, where the radioactive material can be targeted to specific areas of the body to kill cancer cells. Proper handling and disposal of radioactive pellets is essential to protect the health and safety of individuals and the environment.
What is the daughter product of nuclear decay?
The daughter product of nuclear decay is a new element or isotope that is formed as a result of the original radioactive material decaying.
What is an autoradiogram?
An autoradiogram is another word for an autoradiograph - a photograph image produced by placing a film in contact with a specimen containing radioactive material.
What happens to the decayed portion of a radioactive element after the element reached it's half life?
When a radioactive material undergoes radioactive decay, except spontaneous fission, a daughter product is formed. The daughter may or may not be radioactive. If it is, this daughter product begins its own evolution according to its decay scheme and its own half-life. Any daughter products from that decay event will either be stable or will decay according to how (un)stable the daughter is and what its half-life happens to be. The original radionuclide continues to decay in its own way. You can see a "dynamic" developing here. The fact that a radioactive material has a half-life doesn't speak to what happens to the material or to its daughter products. It is only a measure of the rate of decay of a material. Radioactive materials decay according to what they are, and their daughter products will, if they are not stable, undergo decay as well, each according to its own decay scheme. The half-life only puts a timeline on things. And it (the half-life idea) must be applied to each unstable daughter. A consequence of radioactive decay and inspection of the daughter products allows us to use radioactive decay schemes to date materials. There are a number of radionuclides that are useful in doing this, and the decay schemes are well known. We understand the decay rates of the original material and also its daughters, and by counting all of them, we can "rewind time" to the period when they were isolated and state with good accuracy when the material was sequestered. Different methods of dating materials might be applied, depending on the material and its age.
Can radioactive be recycled?
Yes, there are a number of uses for radioactive material. It depends on the type of radioactive material.
In order for radiometric dating to be accurate what must be true about the daughter material at the time a rock formed?
The daughter material must have not been present in the rock at the time it formed. This ensures that any daughter material present in the rock is solely due to the radioactive decay of the parent material since the time of formation.
How many half-lives have occurred in a rock containing one-fourth parent material and three-fourths daughter material?
2 half-lives have.
What waste products come from power stations?
Radioactive waste is a waste product containing radioactive material. It is usually the product of a nuclear process such as nuclear fission, though industries not directly connected to the nuclear power industry may also produce radioactive waste.
