Answer:
The given statement about the air parcel is True
Explanation:
It can be explained as atmospheric pressure on air parcel is higher due to which it contracts when it is close to earth but if the temperature inside the parcel is more than that of the surrounding then due to low density it will rise upward and as the parcel gains height the air pressure exerted by the surrounding on the parcel reduces due to increase in height of the parcel from the earth and hence the air parcel expands. The entire process happens with heat being constant (adiabatic) i.e., amount of heat transferred in the expansion remains same.
Now, the same amount of heat is scattered on the expanded area leading the parcel to cool as it ascends.
Answer:
The correct options are: a. the number of additional neutrons of an isotope is too large; d. the number of additional neutrons of an isotope is too small
Explanation:
The chemical elements that have the same number of protons in the nucleus but different number of neutrons are known as isotopes. Isotopes can be stable or unstable.
The isotope having an unstable nucleus, due to the presence of additional neutrons in the nucleus of the atom, is known as a radioisotope.
Also, chemical elements that have atomic number greater than 83 have unstable nuclei and thus they are called radioisotopes.
The correct answer is - the change of the total volume of water in the Earth's system.
The total volume of the water in the Earth's system is pretty much the same, and for it to change, and change the levels of the water in the oceans and seas, the Earth will have to go over a totally new conditions where either a new influx of water will reach our planet, or the heat will increase and the water will evaporate, for now that is not a possibility.
