The radiation we're dealing with in the Chernobyl area is mostly of the gamma kind. Alpha and beta rays exist as well, but aren't as dangerous unless you eat the berries, drink water from the pond, or inhale lots of dust of the place
The radioactivity of soils, vegetation and waters was increased.
what property of matter has a characteristic that can be measured or observed without changing it idenity
For all materials physical properties are related to some characteristics as density, hardness, refractive index etc. and the chemical properties are related to some characteristics as chemical reactivity, flammability, oxydation etc. Physical properties are characterized by getting back the original material by changing its form, state, etc. Chemical properties are characterized by a complete change in the material itself i.e. you cannot get back the same material.
Human Characteristics: Homes and Schools Physical Characteristics: Sahara Desert
one characteristics that France has is the effil tower
This is a chemical change; but be aware that sometimes the modification of physical characteristics involve a change of material properties.
- a radioactive material emit nuclear radiations as alpha, beta, gamma, neutrons - a radioactive material disintegrate in time
characteristics or chemical and physical properties
yes it has 3 but i don't know them i kow that though Material=fabric Material=physical substance or matter. Material=pertinent. She sewed the material. He handles the radioactive material. That is not material in this case.
The physical properties of materials are not invented, they are intrinsic, natural, specific characteristics of any material.
The distance from origin, and the composition of the source material.
The only one of Gypsum's physical characteristics that can be described as nonmetallic is it's luster. Luster is defined as the way light reflects off of a material.
Radium has chemical properties similar to properties of calcium and barium.
It is diatomic. Being radioactive, and its most stable isotope having a half life of 8.3 hours, it is usually not considered.
Salient characteristics means those particular characteristics that specifically describe the essential physical and functional features of the material or service required. They are features that are identified in the specifications as a mandatory requirement that a proposed "equal" product or material must possess for the bid to be considered responsive.
what property of matter has a characteristic that can be measured or observed without changing it idenity
No, a point does not have physical characteristics.
The resistance of a material depends on:-The material itself.Length of the conductor.Area of cross section of the conductor.Temperature.
