Explanation:
Out of the options given above, the statement that is true is this: YOU ARE EXPOSED TO NUCLEAR RADIATION EVERYDAY.
Man is naturally surrounded by many natural and artificial radioactive sources which give out radiations on a daily basis. Although most people believe that the natural radiation are at levels that are not dangerous, scientific studies had found out that this is not true; some of the radiations are given out at the rate that are harmful to humans.<span />
Explanation:
An allotrope is defined as one or more form of a chemical element that exist in same physical state but different chemical properties.
For example, allotropes of carbon are graphite and diamond. And, both of them exist in a solid state with different chemical properties.
On the other hand, an isotope is two or more forms of an element that contains same number of protons but different number of neutrons.
For example, and are isotopes of hydrogen.
Some of the differences between allotropes and isotopes are as follows.
- Isotopes have different atomic masses but they show similar chemical properties due to the presence of same number of electrons.
- All allotropes are stable molecules that are found in nature. But in case of isotopes, some are stable while some are unstable.
- Almost all elements have isotopes. But all chemical elements does not have allotropes
one or more forms of a chemical element that occur in the same physical state. ... Allotropes may display very different chemical and physical properties. For example, graphite and diamond are both allotropes of carbon that occur in the solid state.
Answer:
It will increase the kinetic energy of gas particles and hence gas will expand.
Explanation:
According to law, there is direct relationship between temperature (thermal energy) of gas and it's volume. When the pressure of gas is held constant and it's temperature increases then the volume of gas also gets increases.
When the temperature ( thermal energy) of gas increases then the kinetic energy of particles of gas also gets increases due to which particles start to collide with the wall of container and with themselves as well which in turn causes gas to expand.
